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-2026-8367 in the wild and no public exploit code.\n\nAffected product: aria2_project aria2c. 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-2026-8367/ (Markdown: https://insights.sbomify.com/CVE-2026-8367/index.md)","id":"CVE-2026-8367","markdown":"https://insights.sbomify.com/CVE-2026-8367/index.md","name":"CVE-2026-8367","record":{"aliases":["DEBIAN-CVE-2026-8367","GHSA-rpx3-3f8j-f6v2","JLSEC-2026-1347","UBUNTU-CVE-2026-8367"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"aria2c download utility","requires_auth":"none","summary":"Attackers can bypass TLS certificate validation by reusing certificates with incorrect Extended Key Usage, enabling man-in-the-middle attacks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"aria2","vendor":"aria2_project"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"aria2c accepts a server certificate with incorrect Extended Key Usage (EKU).
