• Severity: medium (CVSS 4.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-30 · updated 2026-10-25
• Weakness: CWE-862

Description

CVAT before 2.69.0 contains an improper authorization vulnerability in QualityReportViewSet.get_queryset that allows authenticated attackers to enumerate quality report identifiers belonging to other organizations by exploiting a missing check_object_permissions call on the parent_id query parameter of the quality reports API endpoint. Attackers can send requests with sequential integer parent_id values and distinguish between existing and non-existing reports via HTTP 500 versus HTTP 404 response differences, disclosing cross-organization report existence without returning report content.
