An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44542 exists.\n\nAffected packages and fixed versions:\n- github.com/gtsteffaniak/filebrowser (Go): affected all versions; fixed in 0.0.0-20260501183844-112740bdd41d\n- github.com/gtsteffaniak/filebrowser (Go): affected all versions; fixed in 0.0.0-20260501183844-112740bdd41d\n- github.com/gtsteffaniak/filebrowser (Go): affected all versions; fixed in 0.0.0-20260501183844-112740bdd41d\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-2026-44542/ (Markdown: https://insights.sbomify.com/CVE-2026-44542/index.md)","id":"CVE-2026-44542","markdown":"https://insights.sbomify.com/CVE-2026-44542/index.md","name":"CVE-2026-44542","record":{"aliases":["GHSA-fwj3-42wh-8673","GO-2026-5383"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"FileBrowser Quantum","requires_auth":"none","summary":"Unauthenticated attackers with a valid share hash can delete arbitrary files outside the shared directory due to improper path sanitization.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"filebrowser_quantum","vendor":"gtsteffaniak"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.3.1-stable and 1.3.9-beta, attacker-controlled path input is joined with a trusted base path prior to sanitization, allowing traversal sequences (e.g., ../) to escape the intended shared directory. As a result, an unauthenticated attacker possessing a valid public share hash with delete permissions enabled can delete arbitrary files outside the shared directory within the share owner’s configured storage scope. This affects public/api/resources and public/api/resources/bulk. This vulnerability is fixed in 1.3.1-stable and 1.3.9-beta.","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":"FileBrowser Quantum: Unauthenticated Path Traversal in Public Share Delete Allows Arbitrary File Deletion","id":"CVE-2026-44542","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Local Path Provisioner: HelperPod Template Injection","id":"CVE-2026-44543"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260501183844-112740bdd41d"],"introduced":["0"],"last_affected":[],"package":"github.com/gtsteffaniak/filebrowser","purl":null,"source":"GHSA-fwj3-42wh-8673"},{"ecosystem":"Go","fixed":["0.0.0-20260501183844-112740bdd41d"],"introduced":["0"],"last_affected":[],"package":"github.com/gtsteffaniak/filebrowser","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser","source":"GHSA-fwj3-42wh-8673"},{"ecosystem":"Go","fixed":["0.0.0-20260501183844-112740bdd41d"],"introduced":["0"],"last_affected":[],"package":"github.com/gtsteffaniak/filebrowser","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser","source":"GO-2026-5383"}],"prev":{"headline":"Fides: DOM-based XSS vulnerability in fides.js via fides_description override","id":"CVE-2026-44541"},"products":["filebrowser"],"published":"2026-05-14","related":[{"cvss_score":7.1,"headline":"FileBrowser Quantum: Password Protection Not Enforced on Shared File Links","id":"CVE-2026-27611","kev_date_added":null,"published":"2026-02-25"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["gtsteffaniak"]},"summary":"Unauthenticated attackers with a valid share hash can delete arbitrary files outside the shared directory due to improper path sanitization.","url":"https://insights.sbomify.com/CVE-2026-44542/"}
