An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-67279 in the wild since at least 25 Sep 2026.\n\nAffected product: Mikrotik Routeros. 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-2026-67279/ (Markdown: https://insights.sbomify.com/CVE-2026-67279/index.md)","id":"CVE-2026-67279","markdown":"https://insights.sbomify.com/CVE-2026-67279/index.md","name":"CVE-2026-67279","record":{"aliases":["GHSA-pqp3-gjgf-83cf","openSUSE-SU-2026:11737-1"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_modify","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MikroTik RouterOS","requires_auth":"none","summary":"Unauthenticated attackers can bypass SSH authentication to create, overwrite, or reconstruct files in MikroTik RouterOS, exposing configuration and diagnostic data.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[{"product":"routeros","vendor":"mikrotik"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-841","name":"Improper Enforcement of Behavioral Workflow"}],"description":"RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request.
