{"cve":"CVE-2025-53835","nvd":{"published":"2025-07-14T23:15:25.090","modified":"2026-06-17T09:39:00.223","status":"Analyzed","description":"XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Starting in version 5.4.5 and prior to version 14.10, the XHTML syntax depended on the `xdom+xml/current` syntax which allows the creation of raw blocks that permit the insertion of arbitrary HTML content including JavaScript. This allows XSS attacks for users who can edit a document like their user profile (enabled by default). This has been fixed in version 14.10 by removing the dependency on the `xdom+xml/current` syntax from the XHTML syntax. Note that the `xdom+xml` syntax is still vulnerable to this attack. As it's main purpose is testing and its use is quite difficult, this syntax shouldn't be installed or used on a regular wiki. There are no known workarounds apart from upgrading.","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","CWE-80"],"references":["https://github.com/xwiki/xwiki-rendering/commit/a4ca31f99f524b9456c64150d6f375984aa81ea7","https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-w3wh-g4m9-783p","https://jira.xwiki.org/browse/XRENDERING-660","https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-w3wh-g4m9-783p"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T22:04:28.436527499+00:00"},"epss":{"cve":"CVE-2025-53835","score":0.00408,"percentile":0.3513,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w3wh-g4m9-783p","url":"https://osv.dev/vulnerability/GHSA-w3wh-g4m9-783p","summary":"XWiki Rendering is vulnerable to XSS attacks through insecure XHTML syntax","modified":"2026-09-10T03:50:26.354193801Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.rendering:xwiki-rendering-syntax-xhtml","purl":"pkg:maven/org.xwiki.rendering/xwiki-rendering-syntax-xhtml","ranges":[">=5.4.5 <14.10"],"fixed":["14.10"]}]}],"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).
