{"id":"CVE-2026-57491","summary":"FileRise: ZIP extraction writes blocked file extensions to disk, bypassing the upload blocklist","details":"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.","aliases":["GHSA-c4g2-8fg6-5xrr"],"modified":"2026-10-15T10:47:30.217791310Z","published":"2026-10-14T20:17:04.140Z","database_specific":{"cwe_ids":["CWE-434"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57491.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57491.json"},{"type":"FIX","url":"https://github.com/error311/FileRise/commit/f7114ca2a4e624238dda0d097a07ad6b05c11bb6"},{"type":"WEB","url":"https://github.com/error311/FileRise/releases/tag/v3.16.0"},{"type":"ADVISORY","url":"https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57491"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/error311/filerise","events":[{"introduced":"0"},{"fixed":"85ab7e28083b91b21437ea3a63ed99a124b65929"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.16.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.15.0","v3.14.0","v3.13.0","v3.12.0","v3.11.2","v3.11.1","v3.11.0","v3.10.0","v3.9.4","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.0","v3.7.0","v3.6.1","v3.6.0","v3.5.2","v3.5.1","v3.5.0","v3.4.1","v3.4.0","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.1.7","v3.1.6","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.13.1","v2.13.0","v2.12.1","v2.12.0","v2.11.4","v2.11.3","v2.11.2","v2.11.1","v2.11.0","v2.10.5","v2.10.4","v2.10.1","v2.9.3","v2.9.2","v2.8.0","v2.7.1","v2.7.0","v2.6.2","v2.6.1","v2.5.2","v2.5.1","v2.5.0","v2.4.0","v2.3.7","v2.3.6","v2.3.5","v2.3.4","v2.3.2","v2.3.1","v2.3.0","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.1.0","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v1.9.14","v1.9.13","v1.9.12","v1.9.11","v1.9.10","v1.9.9","v1.9.8","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.13","v1.8.12","v1.8.11","v1.8.10","v1.8.9","v1.8.8","v1.8.7","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.6.11","v1.6.10","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.3","v1.5.2","v1.5.1","v1.5.0","1.4.0","v1.3.15","v1.3.13","v1.3.9","v1.3.8","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.8","v1.2.7","v1.2.6","v1.2.5","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57491.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
