There was no check in the author of a JavaScript xobject or StyleSheet xobject added in a XWiki document, so until now it was possible for a user having only Edit Right to create such object and to craft a script allowing to perform some operations when executing by a user with appropriate rights. This has been patched in XWiki 14.9-rc-1 by only executing the script if the author of it has Script rights.","published":"2023-04-15T15:41:56.041Z","modified":"2026-08-08T03:47:44.653795602Z","cvss":{"score":9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":4,"affectedPackages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-skin-skinx","fixedVersion":"14.9-rc-1"}],"fix":{"url":"https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb","label":"xwiki/xwiki-platform@fe65bc3"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-19514"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-19583"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-9119"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29206.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-cmvg-w72j-7phx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29206"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:47:44.653795602Z"}}
