Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-35387 in the wild and no public exploit code.\n\nAffected product: OpenSSH. 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-2026-35387/ (Markdown: https://insights.sbomify.com/CVE-2026-35387/index.md)","id":"CVE-2026-35387","markdown":"https://insights.sbomify.com/CVE-2026-35387/index.md","name":"CVE-2026-35387","record":{"aliases":["AZL-81794","BELL-CVE-2026-35387","DEBIAN-CVE-2026-35387","ECHO-3b5a-4980-c0ad","GHSA-hpxh-vgmp-3qp6","JLSEC-2026-76","UBUNTU-CVE-2026-35387"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSH server","requires_auth":"low_privilege","summary":"OpenSSH misinterprets ECDSA algorithm listings, allowing unintended algorithms if specific configuration options are set.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openssh","vendor":"openbsd"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-670","name":"Always-Incorrect Control Flow Implementation"}],"description":"OpenSSH before 10.3 can use unintended ECDSA algorithms.
