{"cve":"CVE-2026-22033","nvd":{"published":"2026-01-12T18:15:48.837","modified":"2026-06-17T10:19:23.660","status":"Analyzed","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.","cvss_v4":{"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","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79","CWE-284"],"references":["https://github.com/HumanSignal/label-studio/commit/ea2462bf042bbf370b79445d02a205fbe547b505","https://github.com/HumanSignal/label-studio/pull/9084","https://github.com/HumanSignal/label-studio/security/advisories/GHSA-2mq9-hm29-8qch"],"products":["humansignal:label_studio"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2026-22033","score":0.00279,"percentile":0.20412,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2mq9-hm29-8qch","url":"https://osv.dev/vulnerability/GHSA-2mq9-hm29-8qch","summary":"Label Studio is vulnerable to full account takeover by chaining Stored XSS + IDOR in User Profile via custom_hotkeys field","modified":"2026-09-10T03:50:32.309655283Z","packages":[{"ecosystem":"PyPI","name":"label-studio","purl":"pkg:pypi/label-studio","ranges":["<=1.22.0"],"fixed":[]}]},{"id":"PYSEC-2026-1502","url":"https://osv.dev/vulnerability/PYSEC-2026-1502","summary":"Label Studio is vulnerable to full account takeover by chaining Stored XSS + IDOR in User Profile via custom_hotkeys field","modified":"2026-07-07T17:47:16.306823661Z","packages":[{"ecosystem":"PyPI","name":"label-studio","purl":"pkg:pypi/label-studio","ranges":["<=1.22.0"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
