Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-57491 exists.\n\nAffected product: error311 FileRise. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-57491/ (Markdown: https://insights.sbomify.com/CVE-2026-57491/index.md)","id":"CVE-2026-57491","markdown":"https://insights.sbomify.com/CVE-2026-57491/index.md","name":"CVE-2026-57491","record":{"aliases":["GHSA-c4g2-8fg6-5xrr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FileRise file manager","requires_auth":"low_privilege","summary":"Authenticated users can bypass upload restrictions by extracting blocked file extensions from ZIP archives, potentially leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"FileRise: ZIP extraction writes blocked file extensions to disk, bypassing the upload blocklist","id":"CVE-2026-57491","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"FileRise: Setup mode re-activates when users.txt becomes empty, allowing unauthenticated admin creation","id":"CVE-2026-57492"},"packages":[],"prev":{"headline":"FileRise: WebDAV authentication bypasses TOTP/MFA entirely","id":"CVE-2026-57490"},"products":["FileRise"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["error311"]},"summary":"Authenticated users can bypass upload restrictions by extracting blocked file extensions from ZIP archives, potentially leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-57491/"}
