{"id":"CVE-2026-23516","state":"PUBLISHED","title":"CVAT vulnerable to XSS via skeleton SVG images","description":"CVAT is an open source interactive video and image annotation tool for computer vision. In versions 2.2.0 through 2.54.0, an attacker is able to execute arbitrary JavaScript in a victim user's CVAT UI session, provided that they are able to create a maliciously crafted label in a CVAT task or project, then get the victim user to either edit that label, or view a shape that refers to that label; and/or get the victim user to upload a maliciously crafted SVG image when configuring a skeleton. This gives the attacker temporary access to all CVAT resources that the victim user can access. Version 2.55.0 fixes the issue.","publishedAt":"2026-01-21T21:38:32.971Z","updatedAt":"2026-02-26T14:44:33.999Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["cvat-ai cvat"],"affected":[{"vendor":"cvat-ai","product":"cvat","versions":[{"version":">= 2.2.0, < 2.55.0","status":"affected"}]}],"references":["https://github.com/cvat-ai/cvat/security/advisories/GHSA-3m7p-wx65-c7mp","https://github.com/cvat-ai/cvat/commit/40800707fe39e3ff76c8d036eb953eb12d764e70"],"weaknesses":["CWE-83"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/23xxx/CVE-2026-23516.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-23516","state":"PUBLISHED","datePublished":"2026-01-21T21:38:32.971Z","dateUpdated":"2026-02-26T14:44:33.999Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-01-13T18:22:43.979Z"},"containers":{"cna":{"title":"CVAT vulnerable to XSS via skeleton SVG images","descriptions":[{"lang":"en","value":"CVAT is an open source interactive video and image annotation tool for computer vision.
