The vulnerability has been addressed in the stated patched versions.
Potential Impact
Successful exploitation allows an attacker with limited privileges (an account in a configured source and ability to change a source connection) to fully compromise any user account in authentik. This leads to complete loss of confidentiality, integrity, and availability of the affected system's authentication mechanism.
Mitigation Recommendations
Upgrade authentik to version 2025.12.6, 2026.2.4, 2026.5.1, or later, where this vulnerability has been patched. No other mitigation guidance is provided, and patching is the recommended remediation.
