CVE-2026-12593 Qt CVE debrief

Who should care

Administrators and users of the affected Dashboard system should be aware of this vulnerability and take steps to mitigate it. This includes reviewing user privileges, ensuring proper authentication and authorization, and monitoring for potential exploitation attempts. Security teams and vulnerability management teams should prioritize this vulnerability for remediation.

Technical summary

The implementation of an internal and undocumented Dashboard API endpoint (POST /api/users/~/{user}/tokens) forgot to ensure an HTTP request for creating an API Token for another user had sufficient permission to do so. A precondition for successful exploitation was a preexisting internal user (with more privileges than the attacker), the attacker knowing its login name and the attacker being able to authenticate to the Dashboard via OAuth/OIDC. The attacker would then have to forge a token creation API request on behalf of the other user and could have authenticated and finalized the token creation with their own OAuth/OIDC credentials.

Defensive priority

High

Recommended defensive actions

• Verify and enforce proper authentication and authorization for all API endpoints.
• Review and restrict access to sensitive API endpoints.
• Implement additional monitoring and logging to detect potential exploitation attempts.
• Ensure that all users have the least privileges necessary to perform their tasks.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
