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.","published_at":"2025-07-14T23:00:35.577000Z","last_modified_at":null,"cvss_v3_score":9.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79","CWE-80"],"nvd_references":["https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-w3wh-g4m9-783p","https://github.com/xwiki/xwiki-rendering/commit/a4ca31f99f524b9456c64150d6f375984aa81ea7","https://jira.xwiki.org/browse/XRENDERING-660"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:27:31.918367Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"xwiki","vendor_name":"xwiki","product_slug":"xwiki-rendering","product_name":"xwiki-rendering","version_start":">= 5.4.5, < 14.10","version_start_inclusive":true,"version_end":">= 5.4.5, < 14.10","version_end_inclusive":true,"cpe23_uri":"cve5:xwiki:xwiki-rendering:>= 5.4.5, < 14.10:>= 5.4.5, < 14.10"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/xwiki/xwiki-rendering/security/advisories/GHSA-w3wh-g4m9-783p","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/xwiki/xwiki-rendering/commit/a4ca31f99f524b9456c64150d6f375984aa81ea7","source_type":"PATCH","tags":["patch"]},{"url":"https://jira.xwiki.org/browse/XRENDERING-660","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2025-07-14T23:00:35.577000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:47:42.774556Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:42.774556Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:42.774556Z","label":"CVSS score revised","source":"cvelistv5"}]}
