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-2026-87794 in the wild and no public exploit code.\n\nAffected product: nfriedly bestzip. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-87794/ (Markdown: https://insights.sbomify.com/CVE-2026-87794/index.md)","id":"CVE-2026-87794","markdown":"https://insights.sbomify.com/CVE-2026-87794/index.md","name":"CVE-2026-87794","record":{"aliases":["GHSA-pf92-m78r-h85c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js zip library","requires_auth":"none","summary":"Attackers can execute arbitrary commands via argument injection in the nativeZip function of the bestzip Node.js library.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"bestzip versions 2.2.6 and 3.0.2 contain an argument injection vulnerability in the nativeZip function that allows attackers to inject arbitrary arguments to the Info-ZIP backend.
