{"id":"GHSA-h36g-93qx-rxgr","summary":"Duplicate Advisory: phpMyFAQ: Stored XSS in FAQ Question/Answer via Encode-Decode Bypass of removeAttributes() Sanitization","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-f5p7-2c9q-8896. This link is maintained to preserve external references.\n\n### Original Description\nphpMyFAQ before 4.1.2 contains a stored cross-site scripting vulnerability in FAQ creation and update endpoints that bypass sanitization through encode-decode cycles. The vulnerability allows authenticated attackers with FAQ_ADD permission to inject malicious script tags via question or answer parameters, which execute in every visitor's browser when FAQ content is rendered with the raw Twig filter.","modified":"2026-09-10T03:50:46.984965723Z","published":"2026-05-15T21:31:32Z","withdrawn":"2026-06-09T00:00:26Z","database_specific":{"github_reviewed_at":"2026-05-21T21:16:40Z","nvd_published_at":"2026-05-15T19:17:03Z","cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-f5p7-2c9q-8896"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46363"},{"type":"PACKAGE","url":"https://github.com/thorsten/phpMyFAQ"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/phpmyfaq-stored-xss-in-faq-question-answer-via-encode-decode-bypass"}],"affected":[{"package":{"name":"phpMyFAQ/phpMyFAQ","ecosystem":"Packagist","purl":"pkg:composer/phpMyFAQ/phpMyFAQ"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.1.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-h36g-93qx-rxgr/GHSA-h36g-93qx-rxgr.json"}},{"package":{"name":"thorsten/phpMyFAQ","ecosystem":"Packagist","purl":"pkg:composer/thorsten/phpMyFAQ"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.1.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-h36g-93qx-rxgr/GHSA-h36g-93qx-rxgr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N/E:X/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"}]}
