An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-20334 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Adaptive Security Appliance (ASA) Software. 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-2026-20334/ (Markdown: https://insights.sbomify.com/CVE-2026-20334/index.md)","id":"CVE-2026-20334","markdown":"https://insights.sbomify.com/CVE-2026-20334/index.md","name":"CVE-2026-20334","record":{"aliases":["GHSA-2vf5-qc6p-8g6v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firewall Software","requires_auth":"high_privilege","summary":"Cisco released a hardening update addressing multiple coding standard violations in firewall software, requiring users to apply the patch for improved security posture.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-710","name":"Improper Adherence to Coding Standards"}],"description":"As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Secure Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense Software and Cisco Secure Firewall Management Center Software engineering team has conducted a comprehensive internal security review.
