{"id":"CVE-2026-57491","published":"2026-10-14T21:17:37.507","lastModified":"2026-10-15T19:17:41.620","description":"FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise archive extraction does not apply UploadNamePolicy::isAllowedForWrite() before ZipArchive::extractTo() writes entries into the destination directory. An authenticated user with upload and extract permissions can place a blocked extension such as a PHP-family file inside a ZIP and cause it to be written to disk even when normal uploads reject that filename. Post-extraction metadata pruning does not remove the blocked file, so deployments that execute uploaded content may permit code execution. This issue is fixed in version 3.16.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://github.com/error311/FileRise/commit/f7114ca2a4e624238dda0d097a07ad6b05c11bb6","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.16.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr","tags":[]}],"exploitRefs":[{"url":"https://github.com/error311/FileRise/commit/f7114ca2a4e624238dda0d097a07ad6b05c11bb6","tags":[]},{"url":"https://github.com/error311/FileRise/releases/tag/v3.16.0","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr","tags":[]},{"url":"https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr","tags":[]}],"hasPoc":true,"ai":null}
