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_at":"2023-04-15T14:24:59.250000Z","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":"poc","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-79"],"nvd_references":["https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j","https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182","https://jira.xwiki.org/browse/XCOMMONS-1680","https://jira.xwiki.org/browse/XCOMMONS-2426","https://jira.xwiki.org/browse/XWIKI-9118"],"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":"2026-06-29T01:29:15.447901Z"},"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-commons","product_name":"xwiki-commons","version_start":">= 4.2-milestone-1, < 14.6-rc-1","version_start_inclusive":true,"version_end":">= 4.2-milestone-1, < 14.6-rc-1","version_end_inclusive":true,"cpe23_uri":"cve5:xwiki:xwiki-commons:>= 4.2-milestone-1, < 14.6-rc-1:>= 4.2-milestone-1, < 14.6-rc-1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182","source_type":"PATCH","tags":["patch"]},{"url":"https://jira.xwiki.org/browse/XCOMMONS-1680","source_type":"MISC","tags":[]},{"url":"https://jira.xwiki.org/browse/XCOMMONS-2426","source_type":"MISC","tags":[]},{"url":"https://jira.xwiki.org/browse/XWIKI-9118","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-04-15T14:24:59.250000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:27:51.475370Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:27:51.475370Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:27:51.475370Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:29:15.447901Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:29:15.447901Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:29:15.447901Z","label":"SSVC decision revised","source":"vulnrichment"}]}
