Prior to 17.4.8 and 17.10.1, an improperly protected scripting API allows any user with script right to bypass the sandboxing of the Velocity scripting API and execute, e.g., arbitrary Python scripts, allowing full access to the XWiki instance and thereby compromising the confidentiality, integrity and availability of the whole instance. Note that script right already constitutes a high level of access that we don't recommend giving to untrusted users. This vulnerability is fixed in 17.4.8 and 17.10.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-862"],"references":["https://github.com/xwiki/xwiki-platform/commit/9fe84da66184c05953df9466cf3a4acd15a46e63","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-h259-74h5-4rh9","https://jira.xwiki.org/browse/XWIKI-23698","https://jira.xwiki.org/browse/XWIKI-23702"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-33229","score":0.0054,"percentile":0.45468,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-h259-74h5-4rh9","url":"https://osv.dev/vulnerability/GHSA-h259-74h5-4rh9","summary":"XWiki vulnerable to remote code execution with script right through unprotected Velocity scripting API","modified":"2026-04-08T19:36:59.002837Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore","ranges":[">=17.0.0-rc-1 <17.4.8"],"fixed":["17.4.8"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore","ranges":[">=17.5.0-rc-1 <17.10.1"],"fixed":["17.10.1"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-legacy-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-legacy-oldcore","ranges":[">=17.0.0-rc-1 <17.4.8"],"fixed":["17.4.8"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-legacy-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-legacy-oldcore","ranges":[">=17.5.0-rc-1 <17.10.1"],"fixed":["17.10.1"]}]}],"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).
