CVE-2026-73221: CWE-863: Incorrect Authorization in cvat-ai cvat
CVAT is an open source interactive video and image annotation tool for computer vision. From 2.17.0 until 2.72.0, a user with the Worker role can use predictable task-based request IDs with the lambda request retrieve and destroy endpoints to view automatic annotation requests for tasks or jobs the user cannot access and cancel requests initiated by other users. This issue is fixed in version 2.72.0.
AI Analysis
Technical Summary
CVAT versions 2.17.0 through 2.71.x contain an incorrect authorization vulnerability (CWE-863) where a user assigned the Worker role can leverage predictable task-based request IDs in lambda request retrieve and destroy endpoints. This flaw enables such users to view automatic annotation requests associated with tasks or jobs beyond their access rights and to cancel requests initiated by other users. The vulnerability is resolved in CVAT version 2.72.0.
Potential Impact
An attacker with Worker role privileges can gain unauthorized visibility into automatic annotation requests for tasks or jobs they are not authorized to access. Additionally, they can cancel annotation requests initiated by other users, potentially disrupting workflows or data integrity. The vulnerability does not allow privilege escalation beyond the Worker role or direct code execution.
Mitigation Recommendations
A fix is available in CVAT version 2.72.0. Users and administrators should upgrade to version 2.72.0 or later to remediate this authorization issue. Since this is a cloud-hosted service, the vendor manages remediation for the cloud environment; users should verify with the vendor that the service is updated accordingly.
