It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-24909 exists.\n\nAffected packages and fixed versions:\n- @vltpkg/tar (npm): affected all versions; fixed in 1.0.0-rc.10\n- @vltpkg/tar (npm): affected all versions; fixed in 1.0.0-rc.10\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-2026-24909/ (Markdown: https://insights.sbomify.com/CVE-2026-24909/index.md)","id":"CVE-2026-24909","markdown":"https://insights.sbomify.com/CVE-2026-24909/index.md","name":"CVE-2026-24909","record":{"aliases":["GHSA-gf2c-jwcj-x929"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"npm package","requires_auth":"none","summary":"Attackers can exploit path traversal in vlt tar extraction to read or modify files outside the intended directory.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"vlt before 1.0.0-rc.10 mishandles path sanitization for tar, leading to path traversal during extraction.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"vlt Mishandles Path Sanitization for tar","id":"CVE-2026-24909","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":2,"n_references":4,"next":{"headline":"Security feature bypass in Bun","id":"CVE-2026-24910"},"packages":[{"ecosystem":"npm","fixed":["1.0.0-rc.10"],"introduced":["0"],"last_affected":[],"package":"@vltpkg/tar","purl":null,"source":"GHSA-gf2c-jwcj-x929"},{"ecosystem":"npm","fixed":["1.0.0-rc.10"],"introduced":["0"],"last_affected":[],"package":"@vltpkg/tar","purl":"pkg:npm/%40vltpkg/tar","source":"GHSA-gf2c-jwcj-x929"}],"prev":{"headline":"OpenEMR has SQL Injection in Patient API Sort Parameter","id":"CVE-2026-24908"},"products":["vlt"],"published":"2026-01-27","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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-28","vendors":["vlt"]},"summary":"Attackers can exploit path traversal in vlt tar extraction to read or modify files outside the intended directory.","url":"https://insights.sbomify.com/CVE-2026-24909/"}
