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-2026-35604 exists.\n\nAffected packages and fixed versions:\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.63.1\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.63.1\n- github.com/filebrowser/filebrowser/v2 (Go): affected all versions; fixed in 2.63.1\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-2026-35604/ (Markdown: https://insights.sbomify.com/CVE-2026-35604/index.md)","id":"CVE-2026-35604","markdown":"https://insights.sbomify.com/CVE-2026-35604/index.md","name":"CVE-2026-35604","record":{"aliases":["GHSA-v9w4-gm2x-6rvf","GO-2026-5659"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"File Browser","requires_auth":"none","summary":"Attackers can access revoked share links because the application fails to re-check owner permissions, allowing unauthorized data retrieval.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"filebrowser","vendor":"filebrowser"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory.
