CVE-2026-54730: CWE-284: Improper Access Control in goauthentik authentik
authentik is an open-source identity provider. Prior to 2026.2.6 and 2026.5.5, the enterprise Google Chrome device-trust stages advance the flow without confirming that the out-of-band device attestation actually ran. Affected enterprise deployments place either a Google Chrome Endpoint stage with mode set to REQUIRED or the deprecated Google Chrome Device Trust Connector stage in an authentication flow. The device attestation occurs in a verification iframe that calls the Google Verified Access API and records the verified device on success, but the vulnerable stages treat the flow as passed as soon as the stage is submitted. An attacker who can reach such a stage, including after primary username and password authentication, can skip the verification iframe and authenticate from a device that was never verified. Where device trust is the only additional factor, that protection is fully bypassed, while other configured factors remain in force. This issue is fixed in versions 2026.2.6 and 2026.5.5.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-54730) affects goauthentik authentik's enterprise Google Chrome device-trust stages before versions 2026.2.6 and 2026.5.5. These stages improperly advance the authentication flow without verifying that the device attestation, performed via a verification iframe calling the Google Verified Access API, completed successfully. Consequently, an attacker who can reach such a stage can skip device verification and authenticate from an unverified device. This bypass fully negates device trust when it is the sole additional factor, though other factors remain effective. The issue is fixed in versions 2026.2.6 and 2026.5.5.
Potential Impact
An attacker able to reach the vulnerable authentication stage can bypass device attestation, allowing authentication from unverified devices. This undermines the device trust factor in affected deployments, potentially enabling unauthorized access where device trust is the only additional factor beyond primary credentials. Other configured authentication factors remain enforced.
Mitigation Recommendations
Upgrade affected authentik deployments to version 2026.2.6 or 2026.5.5 or later, where this issue is fixed. No other mitigation is indicated by the vendor advisory. Patch status is confirmed by the version information in the description.
