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-2025-8021 exists.\n\nAffected packages and fixed versions:\n- files-bucket-server (npm): affected all versions up to 1.2.6; no fix listed\n- files-bucket-server (npm): affected all versions up to 1.2.6; 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-2025-8021/ (Markdown: https://insights.sbomify.com/CVE-2025-8021/index.md)","id":"CVE-2025-8021","markdown":"https://insights.sbomify.com/CVE-2025-8021/index.md","name":"CVE-2025-8021","record":{"aliases":["GHSA-3r3j-4vrw-884j"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js file server","requires_auth":"none","summary":"Attackers can traverse the file system to access files outside the intended directory in the files-bucket-server package.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"All versions of the package files-bucket-server are vulnerable to Directory Traversal where an attacker can traverse the file system and access files outside of the intended directory.","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":"files-bucket-server vulnerable to Directory Traversal","id":"CVE-2025-8021","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":"Bun Shell does not invoke /bin/sh, or any other interpreter, for template literals created with the $ function.","id":"CVE-2025-8022"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.6"],"package":"files-bucket-server","purl":null,"source":"GHSA-3r3j-4vrw-884j"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.6"],"package":"files-bucket-server","purl":"pkg:npm/files-bucket-server","source":"GHSA-3r3j-4vrw-884j"}],"prev":{"headline":"private-ip vulnerable to Server-Side Request Forgery","id":"CVE-2025-8020"},"products":["files-bucket-server"],"published":"2025-07-23","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-07-23","vendors":["n/a"]},"summary":"Attackers can traverse the file system to access files outside the intended directory in the files-bucket-server package.","url":"https://insights.sbomify.com/CVE-2025-8021/"}
