{"id":"CVE-2026-57491","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-57491","generatedAt":"2026-10-28T01:51:58.298Z","title":"Prior to 3.16.0, FileRise archive extraction does not apply UploadNamePolicy::isAllowedForWrite() before ZipArchive::extractTo() writes entries into the destination directory.","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.","published":"2026-10-14T21:17:38.000Z","lastModified":"2026-10-15T19:17:42.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-434"],"affected":[],"epss":{"score":0.00349,"percentile":0.28276,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00287,"percentile":0.19847}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.35%).
