YesWiki before 4.6.7 Authorization Bypass via Comments API editComment
Summary
YesWiki before 4.6.7 contains an authorization bypass vulnerability in the comments API editComment route that allows authenticated low-privilege users to overwrite arbitrary pages or comments by supplying their own page as the pagetag field. Attackers can send a POST request to the api/comments endpoint targeting a victim tag, bypassing per-page write ACLs to replace content and reparent existing pages or comments.

Title
n8n before 1.123.80, 2.39.6, and 2.40.1 Information Disclosure via Credential Test Endpoint
Summary
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an authorization bypass vulnerability in the credential test endpoint that resolves project-scoped variables without validating caller access. Attackers can specify an arbitrary project ID in the request body to interpolate sensitive variables into credential test requests sent to attacker-controlled hosts for exfiltration.

Title
n8n before 1.123.80 Credential Tampering via Duplicate Node IDs
Summary
n8n versions before 1.123.80 contain a credential tampering vulnerability where duplicate node IDs bypass the workflow credential tamper guard. Attackers with editor access to shared workflows can exploit mismatched node ID and name matching to retain victim credentials and redirect secrets to attacker-controlled hosts.

Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 fail to validate credential ownership during inline agent node-tool introspection. Attackers can reference arbitrary credential IDs to decrypt and exfiltrate plaintext secrets to attacker-controlled hosts without ownership verification.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
