{"id":"GHSA-3x4w-mxpf-fhqq","aliases":["CVE-2026-33051"],"title":"Craft CMS Vulnerable to Stored XSS in Revision Context Menu","description":"The revision/draft context menu in the element editor renders the creator’s `fullName` as raw HTML due to the \nuse of `Template::raw()` combined with `Craft::t()` string interpolation. A low-privileged control panel user\n(e.g., Author) can set their fullName to an XSS payload via the profile editor, then create an entry with two\nsaves.\n\nIf an administrator is logged in and executes a specifically crafted payload while an elevated session is active, the attacker’s account can be elevated to administrator.\n\nUsers should update to Craft 5.9.11 with the patch to mitigate the issue.","severity":"medium","score":5.3,"published":"2026-03-18T12:58:23.000Z","modified":"2026-03-20T21:35:34.087Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"craftcms/cms","ranges":[{"events":[{"introduced":"5.9.0-beta.1"},{"fixed":"5.9.11"}],"type":"ECOSYSTEM"}],"versions":["5.9.0","5.9.0-beta.1","5.9.0-beta.2","5.9.1","5.9.10","5.9.2","5.9.3","5.9.4","5.9.5","5.9.6","5.9.7","5.9.8","5.9.9"],"fixed":["5.9.11"]}],"references":["https://github.com/craftcms/cms/security/advisories/GHSA-3x4w-mxpf-fhqq","https://nvd.nist.gov/vuln/detail/CVE-2026-33051","https://github.com/craftcms/cms/commit/f634a9d21edcafd83a6716047d275f985aba6be1","https://github.com/craftcms/cms","https://github.com/craftcms/cms/releases/tag/5.9.11"],"sources":[{"name":"OSV","id":"GHSA-3x4w-mxpf-fhqq","modified":"2026-03-20T21:35:34.087692Z","url":"https://osv.dev/vulnerability/GHSA-3x4w-mxpf-fhqq"}],"assessments":[{"source":"OSV","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.3}]}
