Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Cross-organization report enumeration in CVAT before 2.69.0 exposes the existence of quality reports belonging to other organizations to any authenticated user. The vulnerability stems from a missing authorization gate in QualityReportViewSet.get_queryset, where the parent_id query parameter is processed without invoking check_object_permissions, allowing cross-tenant enumeration via differential HTTP response analysis. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid authenticated session on the CVAT instance (PR:L, confirmed by CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N) scores 5.3 and accurately reflects the limited impact: only report existence is disclosed, not report content, and exploitation requires valid credentials (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user on a shared CVAT instance iterates requests to the quality reports API with sequential parent_id integers: /api/quality/reports?parent_id=1, ?parent_id=2, and so on. HTTP 500 responses reveal that a report with that ID exists (and belongs to another organization), while HTTP 404 responses confirm the ID does not exist. … |
| Remediation | Upgrade CVAT to version 2.69.0, which contains the fix introduced via commit 27953f19d2265f8b495369f816730a7452db791b (PR #10807, https://github.com/cvat-ai/cvat/pull/10807). … Detailed patch versions, workarounds, and compensating controls in full report. |
