Starting in version 9.7-rc-1 and prior to versions 15.10.11, 16.4.1, and 16.5.0, any user with an account can perform arbitrary remote code execution by adding instances of `XWiki.WikiMacroClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0. It is possible to manually apply the patch to the page `XWiki.XWikiSyntaxMacrosList` as a workaround.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94","CWE-96"],"references":["https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-2r87-74cx-2p7c","https://jira.xwiki.org/browse/XWIKI-22030","https://jira.xwiki.org/browse/XWIKI-22030"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T21:57:36.180738747+00:00"},"epss":{"cve":"CVE-2024-55877","score":0.01603,"percentile":0.75833,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2r87-74cx-2p7c","url":"https://osv.dev/vulnerability/GHSA-2r87-74cx-2p7c","summary":"XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList","modified":"2024-12-12T22:33:07Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-help-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-help-ui","ranges":[">=9.7-rc-1 <15.10.11"],"fixed":["15.10.11"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-help-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-help-ui","ranges":[">=16.0.0-rc-1 <16.4.1"],"fixed":["16.4.1"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-help-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-help-ui","ranges":[">=16.5.0-rc-1 <16.5.0"],"fixed":["16.5.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
