Versions 16.10.9 and below, 17.0.0-rc-1 through 17.4.2 and 17.5.0-rc-1 through 17.5.0 have insufficient protection against {{/html}} injection, which attackers can exploit through RCE. Any user who can edit their own profile or any other document can execute arbitrary script macros, including Groovy and Python macros, which enable remote code execution as well as unrestricted read and write access to all wiki contents. This issue is fixed in versions 16.10.10, 17.4.3 and 17.6.0-rc-1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},"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-95"],"references":["https://github.com/xwiki/xwiki-platform/commit/12b780ccd5bca5fc8f74f46648d7e02fa04fbc11","https://github.com/xwiki/xwiki-rendering/commit/9b71a2ee035815cfc29cebbfe81dbdd98f941d49","https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-9xc6-c2rm-f27p","https://jira.xwiki.org/browse/XRENDERING-693","https://jira.xwiki.org/browse/XRENDERING-792"],"products":["xwiki:xwiki-rendering"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-66474","score":0.01021,"percentile":0.63434,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9xc6-c2rm-f27p","url":"https://osv.dev/vulnerability/GHSA-9xc6-c2rm-f27p","summary":"XWiki vulnerable to remote code execution through insufficient protection against {{/html}} injection","modified":"2025-12-20T05:42:42.124240Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.rendering:xwiki-rendering-xml","purl":"pkg:maven/org.xwiki.rendering/xwiki-rendering-xml","ranges":["<16.10.10"],"fixed":["16.10.10"]},{"ecosystem":"Maven","name":"org.xwiki.rendering:xwiki-rendering-xml","purl":"pkg:maven/org.xwiki.rendering/xwiki-rendering-xml","ranges":[">=17.0.0-rc-1 <17.4.3"],"fixed":["17.4.3"]},{"ecosystem":"Maven","name":"org.xwiki.rendering:xwiki-rendering-xml","purl":"pkg:maven/org.xwiki.rendering/xwiki-rendering-xml","ranges":[">=17.5.0-rc-1 <17.6.0-rc-1"],"fixed":["17.6.0-rc-1"]}]}],"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).
