{"cve":"CVE-2023-29201","nvd":{"published":"2023-04-15T15:15:08.273","modified":"2026-06-17T05:49:35.957","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-79"],"references":["https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182","https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j","https://jira.xwiki.org/browse/XCOMMONS-1680","https://jira.xwiki.org/browse/XCOMMONS-2426"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T21:38:05.473481323+00:00"},"epss":{"cve":"CVE-2023-29201","score":0.01153,"percentile":0.66976,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m3jr-cvhj-f35j","url":"https://osv.dev/vulnerability/GHSA-m3jr-cvhj-f35j","summary":"org.xwiki.commons:xwiki-commons-xml Cross-site Scripting vulnerability","modified":"2026-09-10T03:50:01.088287129Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.commons:xwiki-commons-xml","purl":"pkg:maven/org.xwiki.commons/xwiki-commons-xml","ranges":[">=4.2-milestone-1 <14.6-rc-1"],"fixed":["14.6-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).
