{"cve":"CVE-2023-29525","nvd":{"published":"2023-04-19T00:15:09.127","modified":"2026-10-24T13:10:00.147","status":"Modified","description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-74"],"references":["https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766","https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgg7-w2rj-58cj","https://jira.xwiki.org/browse/XWIKI-20287","https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2023-29525","score":0.77752,"percentile":0.99565,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jgg7-w2rj-58cj","url":"https://osv.dev/vulnerability/GHSA-jgg7-w2rj-58cj","summary":"XWiki Platform vulnerable to privilege escalation from view right on XWiki.Notifications.Code.LegacyNotificationAdministration","modified":"2023-11-08T04:12:20.448222Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-distribution-war","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-distribution-war","ranges":[">=12.6.1 <13.10.11"],"fixed":["13.10.11"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-distribution-war","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-distribution-war","ranges":[">=14.0-rc-1 <14.4.8"],"fixed":["14.4.8"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-distribution-war","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-distribution-war","ranges":[">=14.5 <14.6-rc-1"],"fixed":["14.6-rc-1"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-legacy-events-hibernate-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-legacy-events-hibernate-ui","ranges":[">=14.6-rc-1 <14.10.3"],"fixed":["14.10.3"]}]}],"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).
