It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-40030 in the wild and no public exploit code.\n\nAffected product: khyrenz parseusbs. 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-2026-40030/ (Markdown: https://insights.sbomify.com/CVE-2026-40030/index.md)","id":"CVE-2026-40030","markdown":"https://insights.sbomify.com/CVE-2026-40030/index.md","name":"CVE-2026-40030","record":{"aliases":["GHSA-pqxv-pjgq-x85w"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"USB parsing library","requires_auth":"none","summary":"Attackers can execute arbitrary OS commands by providing crafted volume paths to the parseusbs library's volume listing feature.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"parseusbs","vendor":"khyrenz"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"parseusbs before 1.9 contains an OS command injection vulnerability where the volume listing path argument (-v flag) is passed unsanitized into an os.popen() shell command with ls, allowing arbitrary command injection via crafted volume path arguments containing shell metacharacters.
