CyberRota Analysis
AI-GeneratedThe vulnerability affects the Graylog log management platform, specifically the DELETE /users/{userId}/tokens/{idOrToken} endpoint, which improperly checks permissions, allowing authenticated users to delete access tokens belonging to other users, including service accounts and administrators. This unauthorized deletion can compromise the integrity of access-token-based integrations, potentially disrupting services. Organizations using affected versions should prioritize updating to versions 6.3.12, 7.0.7, or 7.1.2 to mitigate this risk.

Original NVD Description
Graylog is a free and open log management platform. From 6.2.0 until 6.3.12, 7.0.7, and 7.1.2, the DELETE /users/{userId}/tokens/{idOrToken} endpoint implemented by UsersResource.revokeToken() in graylog2-server/src/main/java/org/graylog2/rest/resources/users/UsersResource.java checks USERS_TOKENREMOVE permission against the attacker-controlled userId path parameter before resolving the token selected by idOrToken. An authenticated user can provide an authorized userId while accessTokenService.loadById() or accessTokenService.load() resolves a token belonging to another user, including a service account or administrator, after which accessTokenService.destroy() deletes that token without checking AccessToken.getUserName(). The issue does not expose token contents, but unauthorized deletion causes integrity impact and can disrupt access-token-based integrations. This issue is fixed in versions 6.3.12, 7.0.7, and 7.1.2.
