{"id":"CVE-2026-58263","aliases":["GHSA-rxcw-mc6f-6hr3"],"url":"https://o3.security/vulnerability/CVE-2026-58263","summary":"Jodit Editor: Mutation XSS in jodit clean-html via a MathML/style rawtext carrier","details":"Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/<style> carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the editor value, potentially causing Mutation XSS. When an application supplies attacker-influenced HTML to the editor's value-set or insertion paths, the sanitized output still contains a live <img ... onload=...> (or another non-onerror handler such as onfocus). A consumer that renders that output (element.innerHTML = editor.value) executes the handler with no user interaction. This issue has been fixed in version 4.12.28.","published":"2026-07-01T20:35:35.364Z","modified":"2026-08-12T03:51:25.844143927Z","cvss":{"score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"jodit","fixedVersion":"4.12.28"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58263.json"},{"type":"ADVISORY","url":"https://github.com/xdan/jodit/security/advisories/GHSA-rxcw-mc6f-6hr3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58263"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:25.844143927Z"}}
