{"id":"CVE-2026-53529","summary":"LeafWiki vulnerable to stored XSS via search-result title (highlight() returns raw title into dangerouslySetInnerHTML)","details":"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.","aliases":["GHSA-j344-qxqm-wg64"],"modified":"2026-09-11T03:30:49.101976757Z","published":"2026-08-21T21:29:11.952Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53529.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53529.json"},{"type":"ADVISORY","url":"https://github.com/perber/leafwiki/security/advisories/GHSA-j344-qxqm-wg64"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53529"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/perber/leafwiki","events":[{"introduced":"0"},{"fixed":"79a52d6b72e30ebda09d043175b2899bcfda212b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.10.2"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.10.1","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.10","v0.4.9","v0.4.8","v0.4.7","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.3","v0.3.2","v0.3.0","v0.2.0","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53529.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
