Attackers can exploit the newattachment, deleterecord, build, clean, and publish endpoints from a malicious web page to write arbitrary files, delete pages, wipe build output, trigger deployment publication, and via DNS rebinding reach read endpoints to disclose data.","publishedAt":"2026-10-01T18:17:39.168Z","updatedAt":"2026-10-13T11:20:53.724Z","severity":{"score":7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["lektor lektor"],"affected":[{"vendor":"lektor","product":"lektor","packageURL":"pkg:github/akhilrex/podgrab","defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.14","versionType":"semver"},{"version":"3.4.0b1","status":"affected","lessThanOrEqual":"3.4.0b15","versionType":"custom"}],"repo":"https://github.com/lektor/lektor"}],"references":["https://gist.github.com/mansurmavlankulov/c7683e3204e84892e442b0196585d5bb","https://www.vulncheck.com/advisories/lektor-csrf-via-admin-api-endpoints"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104059.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104059","state":"PUBLISHED","datePublished":"2026-10-01T18:17:39.168Z","dateUpdated":"2026-10-13T11:20:53.724Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-10-01T18:02:50.081Z"},"containers":{"cna":{"title":"Lektor 3.3.14 CSRF via Admin API Endpoints","descriptions":[{"lang":"en","value":"Lektor 3.3.14 and 3.4.0b15 contains a cross-site request forgery vulnerability in the admin API blueprint that allows unauthenticated attackers to perform state-changing actions by sending cross-origin requests without CSRF tokens, Origin/Referer validation, CORS configuration, or Host allowlisting.
