CVE-2026-61574: authentik RAC: access any endpoint via an unrelated application
authentik is an open-source identity provider. Prior to 2026.2.6 and 2026.5.5, the Remote Access Control endpoint list returns every configured endpoint to any authenticated user regardless of which applications the user may access, and the response includes connection settings that can contain stored credentials. The endpoint listing does not apply the access controls governing the endpoints, and the connection flow does not confirm that an endpoint belongs to the Remote Access Control application through which it was launched. Any authenticated user can therefore read every endpoint together with its host and stored credentials and can open a connection to an endpoint belonging to another application. This exposes stored credentials for managed RDP, SSH, and VNC targets and grants interactive access to systems the user was never authorized to reach. Deployments that do not use the enterprise Remote Access Control provider are not affected. This issue is fixed in versions 2026.2.6 and 2026.5.5.

Frequently Asked Questions
Which deployments are exposed?
Deployments using the enterprise Remote Access Control provider are affected. Deployments that do not use that provider are not affected.
What level of access does an attacker need to exploit this issue?
An attacker needs only an authenticated authentik account; no interaction from another user is required. They can use an unrelated application to enumerate configured endpoints, obtain connection settings that may include stored credentials, and connect to targets assigned to other applications.
Which versions contain the fix?
Upgrade to authentik version 2026.2.6 or 2026.5.5. These versions fix both the endpoint-list access-control failure and the missing validation that a target belongs to the application used to launch it.
How can teams assess whether the issue may already have been exploited?
Review whether any authenticated user could have accessed Remote Access Control endpoint listings or launched connections through applications not authorized for the target. Because exposed endpoint settings can contain stored credentials and enable interactive RDP, SSH, or VNC access, investigate potential access to all managed targets and credential exposure.
