{"id":"GHSA-793w-g325-hrw2","summary":"XWiki Platform vulnerable to persistent Cross-site Scripting through CKEditor Configuration pages","details":"### Effect\nAny user with edit rights can edit all pages in the `CKEditor' space. This makes it possible to perform a variety of harmful actions, such as\n- removing technical documents, leading to loss of service\n- Editing the javascript configuration of CKEditor, leading to persistent XSS\n\n### Patches\nThis issue has been patched in XWiki 14.10.6 and XWiki 15.1.\nThis issue has been patched on the CKEditor Integration extension 1.64.9 for XWiki version older than 14.6RC1.\n\n### Workarounds\nThe issue can be fixed manually by restricting the `edit` and `delete` rights to a trusted user or group (e.g. the `XWiki.XWikiAdminGroup` group), implicitly disabling those rights for all other users.\nSee https://github.com/xwiki/xwiki-platform/commit/9d9d86179457cb8dc48b4491510537878800be4f\n\n### References\n- https://jira.xwiki.org/browse/XWIKI-20590\n- https://jira.xwiki.org/browse/CKEDITOR-508\n- https://github.com/xwiki/xwiki-platform/commit/9d9d86179457cb8dc48b4491510537878800be4f\n\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n*    Open an issue in [Jira XWiki.org](https://jira.xwiki.org/)\n*    Email us at [Security Mailing List](mailto:security@xwiki.org)","aliases":["CVE-2023-36477"],"modified":"2026-09-10T03:49:53.971414872Z","published":"2023-06-30T20:40:47Z","database_specific":{"nvd_published_at":"2023-06-30T19:15:09Z","cwe_ids":["CWE-79"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2023-06-30T20:40:47Z"},"references":[{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-793w-g325-hrw2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36477"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/9d9d86179457cb8dc48b4491510537878800be4f"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"},{"type":"WEB","url":"https://jira.xwiki.org/browse/CKEDITOR-508"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-20590"}],"affected":[{"package":{"name":"org.xwiki.platform:xwiki-platform-ckeditor-ui","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-ckeditor-ui"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"14.6-rc-1"},{"fixed":"14.10.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/06/GHSA-793w-g325-hrw2/GHSA-793w-g325-hrw2.json"}},{"package":{"name":"org.xwiki.contrib:application-ckeditor-ui","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.contrib/application-ckeditor-ui"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.9"},{"fixed":"1.64.9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/06/GHSA-793w-g325-hrw2/GHSA-793w-g325-hrw2.json"}},{"package":{"name":"org.xwiki.platform:xwiki-platform-ckeditor-ui","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-ckeditor-ui"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"15.0-rc-1"},{"fixed":"15.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/06/GHSA-793w-g325-hrw2/GHSA-793w-g325-hrw2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"}]}
