{"id":"CVE-2023-29201","aliases":["GHSA-m3jr-cvhj-f35j"],"url":"https://o3.security/vulnerability/CVE-2023-29201","summary":"org.xwiki.commons:xwiki-commons-xml Cross-site Scripting vulnerability","details":"XWiki Commons are technical libraries common to several other top level XWiki projects. The \"restricted\" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1, only escaped `<script>` and `<style>`-tags but neither attributes that can be used to inject scripts nor other dangerous HTML tags like `<iframe>`. As a consequence, any code relying on this \"restricted\" mode for security is vulnerable to JavaScript injection (\"cross-site scripting\"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. This problem has been patched in XWiki 14.6 RC1 with the introduction of a filter with allowed HTML elements and attributes that is enabled in restricted mode. There are no known workarounds apart from upgrading to a version including the fix.","published":"2023-04-15T14:24:59.250Z","modified":"2026-08-08T09:06:43.146021Z","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.commons:xwiki-commons-xml","fixedVersion":"14.6-rc-1"}],"fix":{"url":"https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","label":"xwiki/xwiki-commons@4a185e0"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XCOMMONS-1680"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XCOMMONS-2426"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-9118"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29201.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29201"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T09:06:43.146021Z"}}
