{"id":"CVE-2026-22033","state":"PUBLISHED","title":"Label Studio vulnerable to full account takeover by chaining Stored XSS + IDOR in User Profile via custom_hotkeys field","description":"Label Studio is a multi-type data labeling and annotation tool. In 1.22.0 and earlier, a persistent stored cross-site scripting (XSS) vulnerability exists in the custom_hotkeys functionality of the application. An authenticated attacker (or one who can trick a user/administrator into updating their custom_hotkeys) can inject JavaScript code that executes in other users’ browsers when those users load any page using the templates/base.html template. Because the application exposes an API token endpoint (/api/current-user/token) to the browser and lacks robust CSRF protection on some API endpoints, the injected script may fetch the victim’s API token or call token reset endpoints — enabling full account takeover and unauthorized API access.","publishedAt":"2026-01-12T17:47:34.060Z","updatedAt":"2026-01-12T18:12:36.147Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["HumanSignal label-studio"],"affected":[{"vendor":"HumanSignal","product":"label-studio","versions":[{"version":"<= 1.22.0","status":"affected"}]}],"references":["https://github.com/HumanSignal/label-studio/security/advisories/GHSA-2mq9-hm29-8qch","https://github.com/HumanSignal/label-studio/pull/9084","https://github.com/HumanSignal/label-studio/commit/ea2462bf042bbf370b79445d02a205fbe547b505"],"weaknesses":["CWE-79","CWE-284"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/22xxx/CVE-2026-22033.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-22033","state":"PUBLISHED","datePublished":"2026-01-12T17:47:34.060Z","dateUpdated":"2026-01-12T18:12:36.147Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-01-05T22:30:38.719Z"},"containers":{"cna":{"title":"Label Studio vulnerable to full account takeover by chaining Stored XSS + IDOR in User Profile via custom_hotkeys field","descriptions":[{"lang":"en","value":"Label Studio is a multi-type data labeling and annotation tool.
