{"id":"CVE-2025-24017","aliases":["GHSA-wphc-5f2j-jhvg"],"url":"https://o3.security/vulnerability/CVE-2025-24017","summary":"YesWiki Vulnerable to Unauthenticated DOM Based XSS","details":"YesWiki is a wiki system written in PHP. Versions up to and including 4.4.5 are vulnerable to any end-user crafting a DOM based XSS on all of YesWiki's pages which is triggered when a user clicks on a malicious link. The vulnerability makes use of the search by tag feature. When a tag doesn't exist, the tag is reflected on the page and isn't properly sanitized on the server side which allows a malicious user to generate a link that will trigger an XSS on the client's side when clicked. This vulnerability allows any user to generate a malicious link that will trigger an account takeover when clicked, therefore allowing a user to steal other accounts, modify pages, comments, permissions, extract user data (emails), thus impacting the integrity, availability and confidentiality of a YesWiki instance. Version 4.5.0 contains a patch for the issue.","published":"2025-01-21T15:37:58.654Z","modified":"2026-08-12T03:51:44.654374284Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"yeswiki/yeswiki","fixedVersion":"4.5.0"}],"fix":{"url":"https://github.com/YesWiki/yeswiki/commit/c1e28b59394957902c31c850219e4504a20db98b","label":"YesWiki/yeswiki@c1e28b5"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/24xxx/CVE-2025-24017.json"},{"type":"ADVISORY","url":"https://github.com/YesWiki/yeswiki/security/advisories/GHSA-wphc-5f2j-jhvg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-24017"},{"type":"FIX","url":"https://github.com/YesWiki/yeswiki/commit/c1e28b59394957902c31c850219e4504a20db98b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.654374284Z"}}
