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-2026-32758 exists.\n\nAffected packages and fixed versions:\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.62.0\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.62.0\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.62.0\n- github.com/filebrowser/filebrowser (Go): affected all versions; no fix listed\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-2026-32758/ (Markdown: https://insights.sbomify.com/CVE-2026-32758/index.md)","id":"CVE-2026-32758","markdown":"https://insights.sbomify.com/CVE-2026-32758/index.md","name":"CVE-2026-32758","record":{"aliases":["GHSA-9f3r-2vgw-m8xp","GO-2026-4711"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"File Browser","requires_auth":"low_privilege","summary":"Authenticated users can bypass access rules to write or move files into restricted paths via path traversal in the rename destination parameter.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"filebrowser","vendor":"filebrowser"}],"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-863","name":"Incorrect Authorization"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Versions 2.61.2 and below are vulnerable to Path Traversal through the resourcePatchHandler (http/resource.go). The destination path in resourcePatchHandler is validated against access rules before being cleaned/normalized, while the actual file operation calls path.Clean() afterward—resolving .. sequences into a different effective path. This allows an authenticated user with Create or Rename permissions to bypass administrator-configured deny rules (both prefix-based and regex-based) by injecting .. sequences in the destination parameter of a PATCH request. As a result, the user can write or move files into any deny-rule-protected path within their scope. However, this cannot be used to escape the user's BasePathFs scope or read from restricted paths. This issue has been fixed in version 2.62.0.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"File Browser has an Access Rule Bypass via Path Traversal in Copy/Rename Destination Parameter","id":"CVE-2026-32758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"File Browser TUS Negative Upload-Length Fires Post-Upload Hooks Prematurely","id":"CVE-2026-32759"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/filebrowser/filebrowser","purl":"pkg:golang/github.com/filebrowser/filebrowser","source":"GO-2026-4711"},{"ecosystem":"Go","fixed":["2.62.0"],"introduced":["0"],"last_affected":[],"package":"github.com/filebrowser/filebrowser/v2","purl":null,"source":"GHSA-9f3r-2vgw-m8xp"},{"ecosystem":"Go","fixed":["2.62.0"],"introduced":["0"],"last_affected":[],"package":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","source":"GHSA-9f3r-2vgw-m8xp"},{"ecosystem":"Go","fixed":["2.62.0"],"introduced":["0"],"last_affected":[],"package":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","source":"GO-2026-4711"}],"prev":{"headline":"Admidio: HTMLPurifier Bypass in eCard Message Allows HTML Email Injection","id":"CVE-2026-32757"},"products":["filebrowser"],"published":"2026-03-19","related":[{"cvss_score":10,"headline":"File Browser Self Registration Grants Any User Admin Access When Default Permissions Include Admin","id":"CVE-2026-32760","kev_date_added":null,"published":"2026-03-19"},{"cvss_score":9.1,"headline":"File Browser: TUS Delete Endpoint Bypasses Delete Permission Check","id":"CVE-2026-29188","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":9,"headline":"Cross-site scripting in n/a","id":"CVE-2023-39612","kev_date_added":null,"published":"2023-09-16"},{"cvss_score":8.9,"headline":"FileBrowser Quantum: Stored XSS in public share page via unsanitized share metadata (text/template misuse)","id":"CVE-2026-30934","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery in Filebrowser","id":"CVE-2021-46398","kev_date_added":null,"published":"2022-02-04"},{"cvss_score":8.2,"headline":"File Browser share links remain accessible after Share/Download permissions are revoked","id":"CVE-2026-35604","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":8.1,"headline":"File Browser: Proxy auth auto-provisioned users inherit Execute permission and Commands","id":"CVE-2026-35607","kev_date_added":null,"published":"2026-04-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-03-20","vendors":["filebrowser"]},"summary":"Authenticated users can bypass access rules to write or move files into restricted paths via path traversal in the rename destination parameter.","url":"https://insights.sbomify.com/CVE-2026-32758/"}
