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-2025-67364 exists.\n\nAffected packages and fixed versions:\n- fast-filesystem-mcp (npm): affected all versions up to 3.4.0; no fix listed\n- fast-filesystem-mcp (npm): affected all versions up to 3.4.0; 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-2025-67364/ (Markdown: https://insights.sbomify.com/CVE-2025-67364/index.md)","id":"CVE-2025-67364","markdown":"https://insights.sbomify.com/CVE-2025-67364/index.md","name":"CVE-2025-67364","record":{"aliases":["GHSA-j893-m93w-jwjw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js filesystem library","requires_auth":"none","summary":"Attackers can bypass directory restrictions via symlinks to read unauthorized files in fast-filesystem-mcp.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fast-filesystem-mcp","vendor":"efforthye"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-24","name":"Path Traversal: '../filedir'"}],"description":"fast-filesystem-mcp version 3.4.0 contains a critical path traversal vulnerability in its file operation tools including fast_read_file. This vulnerability arises from improper path validation that fails to resolve symbolic links to their actual physical paths. The safePath and isPathAllowed functions use path.resolve() which does not handle symlinks, allowing attackers to bypass directory access restrictions by creating symlinks within allowed directories that point to restricted system paths. When these symlinks are accessed through valid path references, the validation checks are circumvented, enabling access to unauthorized files.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"fast-filesystem-mcp has a Path Traversal vulnerability","id":"CVE-2025-67364","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":2,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2025-67366"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["3.4.0"],"package":"fast-filesystem-mcp","purl":null,"source":"GHSA-j893-m93w-jwjw"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["3.4.0"],"package":"fast-filesystem-mcp","purl":"pkg:npm/fast-filesystem-mcp","source":"GHSA-j893-m93w-jwjw"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-67349"},"products":["n/a"],"published":"2026-01-07","related":[],"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":"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":"2026-01-07","vendors":["n/a"]},"summary":"Attackers can bypass directory restrictions via symlinks to read unauthorized files in fast-filesystem-mcp.","url":"https://insights.sbomify.com/CVE-2025-67364/"}
