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.","state":0,"publishedAt":"2026-10-14T20:17:04.14+00:00","modifiedAt":"2026-10-15T18:52:12.8+00:00","affected":[{"ecosystem":"Vendor product","name":"FileRise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"error311\",\n                    \"product\": \"FileRise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.16.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/error311/FileRise/security/advisories/GHSA-c4g2-8fg6-5xrr","https://github.com/error311/FileRise/commit/f7114ca2a4e624238dda0d097a07ad6b05c11bb6","https://github.com/error311/FileRise/releases/tag/v3.16.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57491","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57491","identifiers":["CVE-2026-57491"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
