Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations. The requests are triggered while the gateway renders message content that references external resources. Depending on the services reachable from the gateway, this could disclose sensitive internal information or trigger unintended actions on internal systems.

Title
Kiteworks Email Protection Gateway improper authentication
Summary
Improper authentication in a Kiteworks Email Protection Gateway administrative service. An administrative service in Kiteworks Email Protection Gateway did not consistently enforce administrator authentication, so the required password check could be bypassed. An attacker who referenced a valid administrator account could potentially create, modify, or delete internal users and managed domains and change their security-feature configuration without authenticating; deleting a managed domain also removes its user accounts and could lock administrators out of the gateway.

Title
Kiteworks Core user impersonation in a file-request feature
Summary
Kiteworks Core contains a business logic flaw in a Kiteworks file-request feature allowed an authenticated user to send a request that appeared to originate from another user, because the server did not verify that the requester was authorized to act as the specified account. This could be used to solicit files or information from a recipient under a trusted identity; exploitation requires the feature to be enabled for the attacker's profile and the targeted recipient to act on the request.

CVE-2026-102110 (GCVE-0-2026-102110)
Vulnerability from cvelistv5 – Published: 2026-09-30 20:21 – Updated: 2026-10-01 13:37

Title
Missing authentication on a Kiteworks appliance setup function
Summary
An endpoint used during initial appliance setup did not require authentication and did not correctly enforce its intended state precondition, so during the initial activation window an unauthenticated network attacker could repeatedly re-trigger the privileged activation process. This could disrupt setup and leave the appliance in an incompletely configured state. The issue is only reachable while an appliance is being activated for the first time and not yet fully configured.

Kiteworks Core Improper Validation of Specified Quantity in Input
Summary
Kiteworks did not enforce the maximum permitted value for a configurable security-policy setting. An authenticated administrator could set this value outside its intended range so that the associated control never activated, while the control continued to appear enabled in the administrative interface and audit log, allowing it to be silently rendered ineffective.

Title
Kiteworks Core Local Privilege Escalation
Summary
A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.

Title
Kiteworks Core Authentication Bypass in the Password Reset Workflow
Summary
Kiteworks Core did not correctly validate a parameter submitted to the password reset workflow. An unauthenticated attacker who knew the email address of a user with a locally stored password could potentially reset that account's password without access to the emailed reset link and then authenticate as that user, including where the account holds administrative privileges.

Title
Kiteworks Core Remote Code Execution
Summary
On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.

Title
Kiteworks Core OS Command Injection
Summary
A privilege escalation vulnerability in Kiteworks could have allowed an attacker who had already obtained code execution on one node of a clustered Kiteworks deployment to run operating system commands with elevated privileges on another node of the same cluster. Insufficient input validation in an internal cluster management function let attacker-supplied values reach a privileged execution context; exploitation requires existing access to a node in the cluster, and the affected function is not reachable from outside the cluster.

Kiteworks Secure Data Forms Exposure of Sensitive Information to an Unauthorized Actor
Summary
A form-rendering interface in the Advanced Forms component is reachable without authentication so that published forms can be displayed to anonymous visitors, but it returned more data than the form itself required. Anyone who knew the web address of a published form could potentially retrieve the form owner's Kiteworks account profile, including personal details, along with parts of the deployment's configuration settings; no passwords, authentication tokens, or multi-factor secrets were exposed.

Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations. The requests are triggered while the gateway performs an online certificate status check for an inbound message. Depending on the services reachable from the gateway, this could disclose sensitive internal information or disrupt gateway operation.

Title
Kiteworks Core Path Traversal
Summary
A Kiteworks appliance setup interface did not confine a user-supplied file path to its intended directory, which could allow an unauthenticated attacker to write a file to any location writable by the affected service account, potentially compromising the integrity of the appliance or rendering it unavailable until an operator intervenes. Exploitation requires network access to the affected interface, which is not reachable on a fully configured appliance in its default configuration; reaching it depends on either the transient window while an appliance is first being provisioned or a non-default appliance configuration.

Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations. The requests are triggered while the gateway retrieves a certificate revocation list in an inbound message. Depending on the services reachable from the gateway, this could disclose sensitive internal information or disrupt gateway operation.

Title
Kiteworks Core Sandbox Escape
Summary
The sandbox that isolates document conversion on a Kiteworks appliance did not fully confine the code running inside it. Code already executing within that sandbox could potentially escape its confinement and act with the privileges of the service account that runs the application, which could allow an attacker in that position to read or modify application data and configuration, or to disrupt the service on the affected appliance.

Title
Kiteworks Core Stored Cross-site Scripting (XSS)
Summary
A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an administrator holding only a single, narrowly scoped delegated permission to store crafted content that later executes arbitrary JavaScript in the authenticated session of a System Administrator who views the affected page. This could have permitted the lower-privileged administrator to escalate to full administrative control of the tenant, including the creation of a new administrative account.

Kiteworks Email Protection Gateway Improper Restriction of XML External Entity Reference
Summary
An XML parser used by Kiteworks Email Protection Gateway did not restrict external entity references. Where an optional, non-default message-processing feature is enabled, a remote and unauthenticated sender could potentially use a crafted message to read files accessible to the gateway service account, including cryptographic key material and credentials, and have them sent to a destination they control.

Kiteworks Core Privilege Escalation through Improper Access Control
Summary
An administrative import function in Kiteworks Core did not verify that the requesting administrator was entitled to create the privileged integration credential being imported. A delegated administrator holding a single narrowly scoped administrative permission could therefore obtain full system administrator privileges, without any action by an existing system administrator.
