From 13.4-rc-1 until 16.10.17, 17.4.10, 17.10.4, and 18.1.0-rc-1, the Live Data edit REST API allows a user who can edit a page to change that page's rights without executing the normal document-saving authorization checks. The user can grant script right and then execute potentially dangerous Velocity scripts or send unfiltered HTML and JavaScript to clients. The same missing checks can circumvent extension security controls implemented as listeners for UserUpdatingDocumentEvent and related user document events. This issue is fixed in versions 16.10.17, 17.4.10, 17.10.4, and 18.1.0-rc-1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-862"],"references":["https://github.com/xwiki/xwiki-platform/commit/1ddb954767e50782be960b953b012c1242f6843b","https://github.com/xwiki/xwiki-platform/commit/448b0f074cc6711410eb2647c4740454c92d1626","https://github.com/xwiki/xwiki-platform/commit/778b82b4806ce7ebddb775f953545ff73b841f8b","https://github.com/xwiki/xwiki-platform/commit/fbad7dac8f46c560577e41b9259cbbbbd343e6fc","https://github.com/xwiki/xwiki-platform/releases/tag/xwiki-platform-16.10.17"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-53966","score":0.00768,"percentile":0.55301,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-45ph-gxxr-gwgw","url":"https://osv.dev/vulnerability/GHSA-45ph-gxxr-gwgw","summary":"XWiki Platform Live Data Live Table Connector has privilege escalation from edit to script right through Live Data editing","modified":"2026-08-19T19:33:55.024335Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livedata-livetable","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-livedata-livetable","ranges":[">=13.4-rc-1 <16.10.17"],"fixed":["16.10.17"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livedata-livetable","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-livedata-livetable","ranges":[">=17.0.0-rc-1 <17.4.10"],"fixed":["17.4.10"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livedata-livetable","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-livedata-livetable","ranges":[">=17.5.0-rc-1 <17.10.4"],"fixed":["17.10.4"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livedata-livetable","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-livedata-livetable","ranges":[">=18.0.0-rc-1 <18.1.0-rc-1"],"fixed":["18.1.0-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).
