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-2021-22921 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected from 12.0.0; fixed in 12.22.2, 14.17.2, 16.4.1\n- node-min (Bitnami): affected from 12.0.0; fixed in 12.22.2, 14.17.2, 16.4.1\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-2021-22921/ (Markdown: https://insights.sbomify.com/CVE-2021-22921/index.md)","id":"CVE-2021-22921","markdown":"https://insights.sbomify.com/CVE-2021-22921/index.md","name":"CVE-2021-22921","record":{"aliases":["BIT-node-2021-22921","BIT-node-min-2021-22921","GHSA-g3w9-g82h-cmp4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Node.js runtime","requires_auth":"none","summary":"Local attackers can escalate privileges on Windows via PATH or DLL hijacking due to improper installation directory permissions.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"node.js","vendor":"nodejs"},{"product":"sinec_infrastructure_network_services","vendor":"siemens"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Node.js before 16.4.1, 14.17.2, and 12.22.2 is vulnerable to local privilege escalation attacks under certain conditions on Windows platforms.
