An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53486 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @xhmikosr/decompress (npm): affected all versions; fixed in 10.2.1\n- @xhmikosr/decompress (npm): affected all versions; fixed in 10.2.1\n- @xhmikosr/decompress (npm): affected from 11.0.0; fixed in 11.1.3\n- @xhmikosr/decompress (npm): affected from 11.0.0; fixed in 11.1.3\n- decompress (npm): affected all versions up to 4.2.1; no fix listed\n- decompress (npm): affected all versions up to 4.2.1; 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-2026-53486/ (Markdown: https://insights.sbomify.com/CVE-2026-53486/index.md)","id":"CVE-2026-53486","markdown":"https://insights.sbomify.com/CVE-2026-53486/index.md","name":"CVE-2026-53486","record":{"aliases":["GHSA-mp2f-45pm-3cg9","MINI-3w3h-8484-5724","MINI-7qv2-q9g9-vqpc","MINI-8m6c-m56h-9vm9","MINI-cp4h-9mph-c469","MINI-f542-479x-j8q6","MINI-h8vp-3vwv-gjvg","ROOT-APP-NPM-CVE-2026-53486"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js decompress library","requires_auth":"none","summary":"Attackers can extract crafted archives to read or write files outside the target directory via symlink and path traversal flaws in the decompress library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink entries are created without checking where targets point, path containment used a string prefix comparison, and file modes failed to remove setuid, setgid, or sticky bits.
