{"id":"GHSA-7pr4-wx9w-mqwr","summary":"Craft CMS Vulnerable to Stored XSS in Entry Types Name","details":"## Summary\n\nStored XSS via Entry Type names. The name is not sanitized when displayed in the Entry Types list.\n\n---\n## Proof of Concept\n\n### Required Permissions (Attacker)\n\n- Admin access (only admins have access to the settings page)\n- `allowAdminChanges` is enabled in production, which is against our [security recommendations](https://craftcms.com/knowledge-base/securing-craft).\n\n### Steps to Reproduce\n1. Log in as an attacker.\n2. Go to **Settings** -\u003e **Entry Types** (`/admin/settings/entry-types`).\n3. Create a new Entry Type.\n4. Set **Name** to:\n```html\n\u003cimg src=x onerror=\"alert('XSS-EntryTypes')\" hidden\u003e\n```\n5. Save the Entry Type, and you’ll be redirected back to the entry types table automatically.\n6. Notice the alert fires when the entry types table renders.","aliases":["CVE-2026-25491"],"modified":"2026-02-09T22:56:19.132894Z","published":"2026-02-09T20:35:10Z","database_specific":{"nvd_published_at":"2026-02-09T20:15:57Z","cwe_ids":["CWE-79"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-02-09T20:35:10Z"},"references":[{"type":"WEB","url":"https://github.com/craftcms/cms/security/advisories/GHSA-7pr4-wx9w-mqwr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25491"},{"type":"WEB","url":"https://github.com/craftcms/cms/commit/cfd6ba0e2ce1a59a02d75cae6558c4ace1ab8bd4"},{"type":"PACKAGE","url":"https://github.com/craftcms/cms"},{"type":"WEB","url":"https://github.com/craftcms/cms/releases/tag/5.8.22"}],"affected":[{"package":{"name":"craftcms/cms","ecosystem":"Packagist","purl":"pkg:composer/craftcms/cms"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0-RC1"},{"fixed":"5.8.22"}]}],"versions":["5.0.0","5.0.0-RC1","5.0.1","5.0.2","5.0.3","5.0.4","5.0.5","5.0.6","5.1.0","5.1.1","5.1.10","5.1.2","5.1.3","5.1.4","5.1.5","5.1.6","5.1.7","5.1.8","5.1.9","5.2.0","5.2.0-beta.1","5.2.0-beta.2","5.2.0-beta.3","5.2.0-beta.4","5.2.0-beta.5","5.2.0-beta.6","5.2.1","5.2.10","5.2.2","5.2.3","5.2.4","5.2.4.1","5.2.5","5.2.6","5.2.7","5.2.8","5.2.9","5.3.0","5.3.0-beta.1","5.3.0-beta.2","5.3.0.1","5.3.0.2","5.3.0.3","5.3.1","5.3.2","5.3.3","5.3.4","5.3.5","5.3.6","5.4.0","5.4.0.1","5.4.1","5.4.10","5.4.10.1","5.4.2","5.4.3","5.4.4","5.4.5","5.4.5.1","5.4.6","5.4.7","5.4.7.1","5.4.8","5.4.9","5.5.0","5.5.0.1","5.5.1","5.5.1.1","5.5.10","5.5.2","5.5.3","5.5.4","5.5.5","5.5.6","5.5.6.1","5.5.7","5.5.8","5.5.9","5.6.0","5.6.0.1","5.6.0.2","5.6.1","5.6.10","5.6.10.1","5.6.10.2","5.6.11","5.6.12","5.6.13","5.6.14","5.6.15","5.6.16","5.6.17","5.6.2","5.6.3","5.6.4","5.6.5","5.6.5.1","5.6.6","5.6.7","5.6.8","5.6.9","5.6.9.1","5.7.0","5.7.0-beta.1","5.7.0-beta.2","5.7.1","5.7.1.1","5.7.10","5.7.11","5.7.2","5.7.3","5.7.4","5.7.5","5.7.6","5.7.7","5.7.8","5.7.8.1","5.7.8.2","5.7.9","5.8.0","5.8.1","5.8.10","5.8.11","5.8.12","5.8.13","5.8.13.1","5.8.13.2","5.8.14","5.8.15","5.8.16","5.8.17","5.8.18","5.8.19","5.8.2","5.8.20","5.8.21","5.8.3","5.8.4","5.8.5","5.8.6","5.8.7","5.8.8","5.8.9"],"database_specific":{"last_known_affected_version_range":"\u003c= 5.8.21","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-7pr4-wx9w-mqwr/GHSA-7pr4-wx9w-mqwr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
