CVE-2026-61574Network attack vector

Credential disclosure and cross-application access via unchecked endpoints

Published Aug 18, 2026 · Updated Aug 19, 2026

Incorrect authorization in authentik before 2026.2.6 or 2026.5.0 through 2026.5.4 allows remote authenticated users to access RAC endpoints. The endpoint list omits endpoint access controls, while the connection flow fails to verify that the selected endpoint belongs to the launched application. Enterprise RAC deployments expose stored RDP, SSH, or VNC credentials and permit interactive access to systems outside the user's authorized applications.
