It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24884 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- compressing (npm): affected all versions; fixed in 1.10.4\n- compressing (npm): affected all versions; fixed in 1.10.4\n- compressing (npm): affected from 2.0.0; fixed in 2.0.1\n- compressing (npm): affected from 2.0.0; fixed in 2.0.1\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-2026-24884/ (Markdown: https://insights.sbomify.com/CVE-2026-24884/index.md)","id":"CVE-2026-24884","markdown":"https://insights.sbomify.com/CVE-2026-24884/index.md","name":"CVE-2026-24884","record":{"aliases":["GHSA-cc8f-xg8v-72m3"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_modify","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js compression library","requires_auth":"none","summary":"Attackers can write arbitrary files to the host filesystem via malicious symlinks in TAR archives, potentially leading to code execution or data modification.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"compressing","vendor":"node-modules"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Compressing is a compressing and uncompressing lib for node. In version 2.0.0 and 1.10.3 and prior, Compressing extracts TAR archives while restoring symbolic links without validating their targets. By embedding symlinks that resolve outside the intended extraction directory, an attacker can cause subsequent file entries to be written to arbitrary locations on the host file system. Depending on the extractor’s handling of existing files, this behavior may allow overwriting sensitive files or creating new files in security-critical locations.
