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-2026-33921 in the wild and no public exploit code.\n\nAffected product: Nozomi Networks Arc. 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-2026-33921/ (Markdown: https://insights.sbomify.com/CVE-2026-33921/index.md)","id":"CVE-2026-33921","markdown":"https://insights.sbomify.com/CVE-2026-33921/index.md","name":"CVE-2026-33921","record":{"aliases":["GHSA-gwvc-2mf6-9jv4"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nozomi Networks Arc","requires_auth":"low_privilege","summary":"Local users can capture network traffic and send raw packets due to insecure Npcap driver permissions in Arc installer.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"The Windows installer deployed Npcap leaving its access restriction option at the insecure default value, so the driver was accessible to every local user of the host instead of being restricted to administrators only.
