{"id":"CVE-2024-55662","aliases":["GHSA-j2pq-22jj-4pm5"],"url":"https://o3.security/vulnerability/CVE-2024-55662","summary":"XWiki allows remote code execution through the extension sheet","details":"XWiki Platform is a generic wiki platform. Starting in version 3.3-milestone-1 and prior to versions 15.10.9 and 16.3.0, on instances where `Extension Repository Application` is installed, any user can execute any code requiring `programming` rights on the server. This vulnerability has been fixed in XWiki 15.10.9 and 16.3.0. Since `Extension Repository Application` is not mandatory, it can be safely disabled on instances that do not use it as a workaround. It is also possible to manually apply the patches from commit 8659f17d500522bf33595e402391592a35a162e8 to the page `ExtensionCode.ExtensionSheet` and to the page `ExtensionCode.ExtensionAuthorsDisplayer`.","published":"2024-12-12T17:25:26.297Z","modified":"2026-08-12T03:51:37.187840857Z","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-repository-server-ui","fixedVersion":"15.10.9"},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-repository-server-ui","fixedVersion":"16.3.0"}],"fix":{"url":"https://github.com/xwiki/xwiki-platform/commit/8659f17d500522bf33595e402391592a35a162e8","label":"xwiki/xwiki-platform@8659f17"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-21890"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/55xxx/CVE-2024-55662.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-j2pq-22jj-4pm5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-55662"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/8659f17d500522bf33595e402391592a35a162e8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:37.187840857Z"}}
