Phproject < 1.8.7 Missing Authorization via Issues REST API
Summary
Phproject before 1.8.7 contains a missing object-level authorization vulnerability in the REST API issue endpoints (single_get, single_comments, single_comments_post) that allows authenticated API key holders to bypass the security.restrict_access confidentiality control by never invoking the allowAccess() authorization routine. Attackers can use a valid API key to read restricted issue contents and comments, including owner and author email addresses, and post unauthorized comments to issues they should not have access to.

Title
MISP: Soft-Deleted Attributes from Other Organizations Exposed via Attribute Search and Paginated View
Summary
MISP contains an improper access control vulnerability in its attribute search and paginated attribute view endpoints.
When a user queries for soft-deleted attributes (e.g., via the deleted-attributes search or the paginated attribute listing), the application returned soft-deleted attributes belonging to events owned by other organizations to any authenticated user who had visibility of the event. The event detail view correctly restricted soft-deleted attribute visibility to the owning organization and sync-permission users, but the attribute search and paginated view code paths lacked this restriction.
Preconditions:
- An authenticated MISP user with at least read access to an event owned by another organization.
- The user issues a query for deleted attributes (search or paginated view with the deleted filter).
Impact:
- Confidentiality: Soft-deleted threat intelligence attributes (e.g., IOCs, indicators, context) from other organizations are disclosed to unauthorized users. This may expose sensitive intelligence that the owning organization intended to remove from general visibility.
Affected versions: MISP versions prior to v2.5.48.

fix: [security] Show soft-deleted attributes only to the | 9673ee1d4db2… |
Fix summary
The fix enforces organizational ownership checks on soft-deleted attribute queries. When a user without sync permission requests deleted attributes, the query is now constrained to only return soft-deleted attributes whose parent event belongs to the requesting user's organization. This aligns the attribute search and paginated view behavior with the existing event view authorization logic.
Patch summary
Two code paths were modified:1. Event.php (fetchPaginatedAttributes): When the deleted filter is active and the user lacks perm_sync, an additional subquery condition is appended requiring the event owner's org_id to match the user's org_id. The original blanket deleted=0 or deleted=1 condition is replaced with an OR/AND structure that permits non-deleted attributes for all users but restricts deleted attributes to the owning org.2. MispAttribute.php (fetchAttributes): In the deleted='only' branch, when the user lacks perm_sync, an additional AND condition Event.org_id = user.org_id is added to the query conditions, scoping results to the user's own organization.
CVSS rationale
AV:N: The vulnerability is exploitable over the network via the MISP web API. AC:L: Exploitation requires only a standard query with the deleted-attribute filter; no race conditions or complex setup. AT:N: No special attack requirements. PR:L: An authenticated user with at least read access to an event owned by another organization is required. UI:N: No victim interaction needed; the data is returned in the API response. VC:L: Confidentiality impact is limited to soft-deleted attributes (a subset of event data) from other organizations; not all data is exposed. VI:N, VA:N: No integrity or availability impact on the vulnerable component. SC:N, SI:N, SA:N: No impact on subsequent components.
Weakness rationale
- CWE-862 The attribute search and paginated view code paths were missing the authorization check that restricts soft-deleted attribute visibility to the owning organization. The event view had this check, but the attribute-level query paths did not, allowing any user with event visibility to retrieve soft-deleted attributes from other organizations.
- CWE-284 More broadly, the application failed to enforce proper access control boundaries between organizations when serving soft-deleted attribute data through specific query endpoints, resulting in cross-organizational information disclosure.
Attack pattern rationale
- CAPEC-126 This CAPEC describes leveraging legitimate application code paths to access or manipulate data beyond intended permissions. The attacker uses the legitimate attribute search and paginated view endpoints (executable code paths) to retrieve soft-deleted attributes from other organizations. The mapping is imperfect because CAPEC-126 emphasizes data alteration, whereas this vulnerability is purely an information disclosure. However, among available CAPEC patterns, this is the closest match for exploiting a legitimate code path to bypass intended access restrictions. No CAPEC specifically covers 'information disclosure via missing authorization in a query endpoint' with greater precision.
Assumptions to verify
- The exact fixed version is not specified in the patch metadata; the fix commit is 37 commits after the v2.5.48 tag, so the fixed release is post-2.5.48 but the exact version number is unknown.
- PR:L assumes the attacker needs at least read access to an event owned by another organization; if MISP deployments restrict cross-org event visibility more tightly, the effective privilege requirement may be higher.
- CAPEC-126 is the closest available mapping but is not a perfect fit; the vulnerability is an information disclosure via missing authorization rather than data alteration.
- VC:L assumes the exposure is limited to soft-deleted attributes (a subset of event data) and does not include active attributes or full event metadata.
- The patch does not specify whether this affects all MISP deployments or only multi-organization configurations; the CVSS assumes a multi-org deployment where cross-org visibility is possible.

Title
MISP Correlation Authorization Bypass Exposes Restricted Event and Attribute Data
Summary
MISP contains an authorization flaw in its correlation handling during attribute searches. When a user performs an attribute search that triggers correlation lookups, the system authorized access to correlated attributes and events based on a stale distribution snapshot stored on the correlation row rather than the live event access control list.
Because the correlation row's distribution columns are a point-in-time copy that lacks a published flag, the authorization check becomes incorrect when an event is subsequently restricted (for example, its sharing group is changed or it is unpublished). As a result, an authenticated user could retrieve attributes and event details belonging to events they no longer have permission to view.
Preconditions:
- An authenticated user with at least read access to some events in the instance.
- The existence of correlations between events, at least one of which has been restricted after the correlation was created.
Impact:
- Confidentiality: exposure of attribute values and event metadata that the user is not authorized to access.
Affected versions: MISP prior to v2.5.48.

fix: [security] Check correlations against the live event ACL | a38b683420d9… |
Fix summary
The fix ensures that correlation-based lookups are authorized against the live event and attribute access control lists rather than the stale distribution snapshot on the correlation row. A new filtering step validates related event IDs against the current event ACL before returning them, and attribute queries for non-admin users now include the live ACL conditions. Additionally, Event and Object fields are stripped from returned attribute results to prevent incidental metadata leakage.
Patch summary
In DefaultCorrelationBehavior.php: (1) runGetRelatedAttributes now builds query conditions that include the live attribute ACL (buildConditions) for non-site-admin users, and ensures Event and Object are contained in the query for proper filtering; (2) after fetching related attributes, Event and Object sub-objects are unset from each result; (3) fetchRelatedEventIds now passes its results through a new __filterVisibleEventIds method that queries the Event model with createEventConditions to verify each event ID is still visible to the user; (4) the new __filterVisibleEventIds method returns the event IDs unchanged for site admins or empty lists, otherwise filters against the live event ACL.
CVSS rationale
Network vector: MISP is a web application accessible over the network. Low complexity: the attacker simply performs a normal attribute search that triggers correlations; no race condition or special setup is needed. No attack requirements: the stale correlation row exists naturally after any event restriction. Low privileges: the attacker needs an authenticated account with read access to at least one event. No user interaction: the attacker initiates the search themselves. High vulnerability-component confidentiality impact: full attribute values and event metadata of restricted events are exposed. No integrity or availability impact on the vulnerable or subsequent components.
Weakness rationale
- CWE-862 The correlation lookup path failed to enforce the current (live) authorization state of the target events and attributes. Access was granted based on a stale snapshot rather than the actual ACL, effectively missing the authorization check for restricted events.
- CWE-284 The access control decision relied on outdated data (the distribution columns copied onto the correlation row) that did not reflect the current published/sharing-group state of the event, leading to improper access control.
Attack pattern rationale
- CAPEC-114 The authorization state used for correlation lookups was incorrectly adjusted (stale) relative to the actual event ACL. An attacker with a legitimate account could exploit this misalignment to access data beyond their intended privilege scope. This is the closest CAPEC pattern; the exact mechanism is a stale authorization snapshot rather than a classic privilege-escalation primitive, so the mapping is approximate.
Assumptions to verify
- The affected version boundary (< 2.5.48) is inferred from the tag_version_boundary metadata (v2.5.48, 38 commits after fix); the exact first affected version is not stated in the patch.
- CVSS PR:L assumes the attacker needs a standard authenticated MISP account with read access to at least one event; no evidence supports a lower or higher privilege requirement.
- CAPEC-114 is the closest available pattern; the actual mechanism is a stale authorization snapshot rather than a classic privilege-escalation vector, so the mapping is approximate.
- The patch does not specify whether the vulnerability requires the event to have been restricted after correlation creation, or whether other state changes (e.g., sharing group modification) also trigger the issue; the commit message mentions 'restricted' as the primary scenario.
- No public exploit or PoC is referenced; exploitation status is assumed to be 'none'.

Title
MISP Information Disclosure via Related Events Listing Bypassing Per-Event Authorization
Summary
MISP contains an authorization bypass in the related events listing functionality. When a user requests the list of events correlated to a given event, the system retrieved related event metadata directly from the correlation table without re-validating the caller's access rights against each related event.
The correlation table stores a snapshot of the event's distribution level and sharing group at the time the correlation was created, and does not carry the published flag. As a result, events that the caller is not permitted to open—because they are unpublished, or because their distribution or sharing group has changed since the correlation was recorded—were still returned with their metadata (title, date, correlating value counts).
Preconditions:
- An authenticated user with access to at least one event in MISP.
- The existence of correlation entries linking that event to other events the user should not be able to view.
Impact:
- Unauthorized disclosure of event metadata (titles, dates, correlation counts) for events the user has no right to access.
- Potential reconnaissance of threat-intelligence event names and timelines across sharing groups.
Affected: MISP versions prior to the fix commit (2ffa97f05).

fix: [security] Scope the related event list to what the | c315cbcd2cad… |
Fix summary
The fix enforces proper per-event authorization on the related events query by applying the user's full access-control conditions (including published status, distribution level, and sharing group membership) to the event lookup, rather than relying solely on the stale distribution snapshot stored in the correlation table. This ensures that only events the caller is currently permitted to read are returned in the related events list.
Patch summary
In EventsController.php (viewRelatedEvents) and Event.php (getRelatedEvents), the query that fetches related event metadata previously used only Event.id IN (relatedEventIds) as the condition. The patch replaces this with a call to createEventConditions($user), which builds the full set of authorization conditions (published flag, distribution, sharing group), and then adds the Event.id filter on top. The stale comment claiming ACL was enforced via the correlation table was removed. Two files changed, 8 insertions, 9 deletions.
CVSS rationale
AV:N: MISP is a network-accessible web application. AC:L: An authenticated user simply requests the related events endpoint; no race condition or complex manipulation is needed. AT:N: No attack-target manipulation required. PR:L: Requires a low-privilege authenticated user with access to at least one event. UI:N: No user interaction needed. VC:L: Disclosure is limited to event metadata (title, date, correlation counts), not full event content or attributes. VI:N, VA:N: No integrity or availability impact. SC:N, SI:N, SA:N: No secondary impacts on other systems. The overall score reflects a low-severity information disclosure requiring authentication.
Weakness rationale
- CWE-862 The related events query did not apply the caller's per-event authorization checks (published status, distribution, sharing group). The system relied on a stale snapshot in the correlation table instead of re-validating access, effectively omitting the authorization step for the returned events.
- CWE-285 Even though some authorization existed (via the correlation table snapshot), it was based on outdated data and lacked the published flag check, making the authorization decision incorrect for events whose access parameters had changed or that were unpublished.
Attack pattern rationale
- CAPEC-126 The attacker leverages the trusted correlation relationship stored in the correlation table. The system treated the correlation entry as a sufficient authorization basis, but the snapshot data was stale and incomplete (missing published flag), allowing access to event metadata the caller should not see. This is the closest CAPEC to the pattern of relying on a trusted data source that does not reflect current authorization state. Uncertainty: no CAPEC perfectly describes 'stale authorization snapshot in a join table'; CAPEC-126 is the best available match.
Assumptions to verify
- The tag_version_boundary (v2.5.48, 50 commits after fix) is used as an approximate upper bound for affected versions; exact version boundaries are not explicitly stated in the patch metadata.
- PR:L assumes the attacker needs only a basic authenticated MISP account with access to at least one event; higher-privilege roles may be required depending on deployment configuration, but the patch does not specify this.
- VC:L assumes the disclosed metadata (event titles, dates, correlation counts) constitutes a low confidentiality impact; in highly sensitive threat-intelligence environments the impact could be rated higher.
- CAPEC-126 is the closest available mapping; no CAPEC precisely describes authorization bypass via a stale snapshot in a correlation/join table.
- The 'published' flag and distribution/sharing group checks are assumed to be the primary authorization mechanisms in MISP's event model, based on the commit message and patch context.
- No public exploit or active exploitation is assumed; the patch does not reference any CVE, advisory, or exploitation evidence.

Title
SiYuan before v3.8.5 Missing Authorization in Save-Path Resolver Endpoints
Summary
SiYuan before v3.8.5 contains a missing authorization vulnerability in the getRefCreateSavePath, getShorthandSavePath, and getDocCreateSavePath endpoints that allows read-only publish visitors to learn unpublished notebook box IDs. Attackers with read-only or anonymous publish access can POST any open notebook ID to receive the global save-box ID and save-path template, revealing a hidden notebook's existence and creation time.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
