Affected versions of xwiki are subject to code injection in the `since` parameter of the `/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration` endpoint. This provides an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. Users are advised to upgrade. Users unable to upgrade may modify the page `XWiki.Notifications.Code.LegacyNotificationAdministration` to add the missing escaping. For versions < 14.6-rc-1 a workaround is to modify the file `<xwikiwebapp>/templates/distribution/eventmigration.wiki` to add the missing escaping.","published_at":"2023-04-18T23:01:46.239000Z","last_modified_at":null,"cvss_v3_score":10.0,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/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-74"],"nvd_references":["https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgg7-w2rj-58cj","https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766","https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70","https://jira.xwiki.org/browse/XWIKI-20287"],"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":"2026-06-29T01:29:30.835753Z"},"effective_severity":"CRITICAL","badges":["epss"],"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":"N","value_label":"None"},{"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-platform","product_name":"xwiki-platform","version_start":"< 14.4.8","version_start_inclusive":true,"version_end":"< 14.4.8","version_end_inclusive":true,"cpe23_uri":"cve5:xwiki:xwiki-platform:< 14.4.8:< 14.4.8"},{"vendor_slug":"xwiki","vendor_name":"xwiki","product_slug":"xwiki-platform","product_name":"xwiki-platform","version_start":">= 14.5.0, < 14.10.3.","version_start_inclusive":true,"version_end":">= 14.5.0, < 14.10.3.","version_end_inclusive":true,"cpe23_uri":"cve5:xwiki:xwiki-platform:>= 14.5.0, < 14.10.3.:>= 14.5.0, < 14.10.3."}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgg7-w2rj-58cj","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70","source_type":"PATCH","tags":["patch"]},{"url":"https://jira.xwiki.org/browse/XWIKI-20287","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-04-18T23:01:46.239000Z","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":"2026-06-29T01:29:30.835753Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:29:30.835753Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:29:30.835753Z","label":"SSVC decision revised","source":"vulnrichment"}]}
