{"id":"CVE-2026-61645","state":"PUBLISHED","title":"Docat has Arbitrary File Upload exists in Upload API","description":"Docat is a tool for hosting versioned static documentation. In the affected implementation, an arbitrary file upload vulnerability in the `Upload API` arises because the API does not validate the `uploaded file path or type`. An attacker can overwrite sensitive configuration files or place malicious files on the Docat web server. Depending on deployment context, uploaded content can enable remote code execution or cross-site scripting intended to steal cookies or redirect users to malicious websites. Version 1.6.0 mitigates filename-based path traversal; remediation of unrestricted file types or deployment-dependent malicious-content effects is not established by the verified patch.","publishedAt":"2026-10-29T21:17:37.532Z","updatedAt":"2026-10-29T21:17:37.532Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["docat-org docat"],"affected":[{"vendor":"docat-org","product":"docat","versions":[{"version":"< 1.6.0","status":"affected"}]}],"references":["https://github.com/docat-org/docat/security/advisories/GHSA-jcxj-j5qf-8crw","https://github.com/docat-org/docat/commit/85fc40e8348c6328f488395d03c779517a0913fd","https://github.com/docat-org/docat/releases/tag/1.6.0"],"weaknesses":["CWE-434"],"ingestedAt":"2026-10-29T23:14:04.755Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61645.json","commit":"dc7676b3f67d6707e4927968546e7e0125ff7ec7","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61645","state":"PUBLISHED","datePublished":"2026-10-29T21:17:37.532Z","dateUpdated":"2026-10-29T21:17:37.532Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T17:38:57.112Z"},"containers":{"cna":{"title":"Docat has Arbitrary File Upload exists in Upload API","descriptions":[{"lang":"en","value":"Docat is a tool for hosting versioned static documentation.
