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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.6% (30-day exploitation probability)+7
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Goauthentik Authentik).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Audit administrative actions and access to resources outside each user’s normal pattern.

What should defenders know first?
CVE-2026-61574 is "authentik RAC: access any endpoint via an unrelated application", rated High. It affects Authentik (Goauthentik); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.8 describes technical severity. EPSS 0.62% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
