CVE-2026-55867 is a medium severity authorization bypass vulnerability in Graylog2's graylog2-server affecting versions from 6.2.0 until fixed in 6.3.12, 7.0.7, and 7.1.2. It allows an authenticated user to delete access tokens belonging to other users, including service accounts or administrators, by exploiting improper permission checks on the DELETE /users/{userId}/tokens/{idOrToken} endpoint. The vulnerability does not expose token contents but can disrupt access-token-based integrations by unauthorized token deletion.
