{"id":"CVE-2026-53529","state":"PUBLISHED","title":"LeafWiki vulnerable to stored XSS via search-result title (highlight() returns raw title into dangerouslySetInnerHTML)","description":"LeafWiki is a self-hosted wiki. Prior to version 0.10.2, page titles returned by the search API could be rendered as raw HTML in the frontend. A user with editor or administrator permissions could create or modify a page title containing an HTML/JavaScript payload. When another user searched for a matching term, the payload could execute in the victim’s browser. The impact depends on deployment configuration. With `--public-access` enabled, unauthenticated visitors could be affected. In authenticated-only deployments, the issue could be used for cross-user XSS against logged-in users who can access search results. The issue has been fixed in version 0.10.2 by ensuring that author-controlled page titles in search results are not interpreted as raw HTML by the browser while preserving search result highlighting.","publishedAt":"2026-08-21T21:29:11.952Z","updatedAt":"2026-08-21T21:42:08.184Z","severity":{"score":4.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["perber leafwiki"],"affected":[{"vendor":"perber","product":"leafwiki","versions":[{"version":"< 0.10.2","status":"affected"}]}],"references":["https://github.com/perber/leafwiki/security/advisories/GHSA-j344-qxqm-wg64"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53529.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53529","state":"PUBLISHED","datePublished":"2026-08-21T21:29:11.952Z","dateUpdated":"2026-08-21T21:42:08.184Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-09T17:30:33.457Z"},"containers":{"cna":{"title":"LeafWiki vulnerable to stored XSS via search-result title (highlight() returns raw title into dangerouslySetInnerHTML)","descriptions":[{"lang":"en","value":"LeafWiki is a self-hosted wiki.
