An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20216 in the wild and no public exploit code.\n\nAffected product: Clamav Clamav. 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-2026-20216/ (Markdown: https://insights.sbomify.com/CVE-2026-20216/index.md)","id":"CVE-2026-20216","markdown":"https://insights.sbomify.com/CVE-2026-20216/index.md","name":"CVE-2026-20216","record":{"aliases":["AZL-92172","DEBIAN-CVE-2026-20216","GHSA-8fx8-2p33-gv76","MINI-5h6c-g84w-c64h","MINI-7mfh-fvf2-p3gp","UBUNTU-CVE-2026-20216"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClamAV antivirus engine","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service by submitting a crafted InstallShield file to ClamAV, terminating the scanning process.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_endpoint","vendor":"cisco"},{"product":"clamav","vendor":"clamav"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A vulnerability in the InstallShield file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device.\r\n\r\nThis vulnerability is due to improper handling of temporary resources during file scanning.
