Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-112112 in the wild and no public exploit code.\n\nAffected product: nic BIRD. 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-2026-112112/ (Markdown: https://insights.sbomify.com/CVE-2026-112112/index.md)","id":"CVE-2026-112112","markdown":"https://insights.sbomify.com/CVE-2026-112112/index.md","name":"CVE-2026-112112","record":{"aliases":["DEBIAN-CVE-2026-112112","GHSA-6jp9-p482-x6c9","UBUNTU-CVE-2026-112112"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":true,"product_category":"BGP routing daemon","requires_auth":"low_privilege","summary":"A BGP peer can bypass IPv6 FlowSpec validation to inject unauthorized traffic filtering or redirection rules, affecting network operators using BIRD.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"An IPv6 FlowSpec validation bypass in the CZ.NIC BIRD Internet Routing Daemon allows an established BGP peer to inject FlowSpec rules matching destinations outside the address space authorized by the unicast-route validation procedure. With validation enabled on the receiving flow6 channel, BIRD fails to reject a destination prefix component with a nonzero offset, contrary to RFC 8956 section 5. It validates a reconstructed prefix with zero-filled skipped bits, although the original FlowSpec component can match a broader set of IPv6 addresses. Given a suitable unicast route from the peer, the rule can pass validation and, where export policy permits, be propagated to downstream peers. Downstream enforcement may cause unauthorized traffic filtering or redirection.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in BIRD","id":"CVE-2026-112112","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"diem-project diem dmCodeEditor actions.class.php join path traversal","id":"CVE-2026-112138"},"packages":[],"prev":{"headline":"Cross-site scripting in Bootstrap Shortcodes","id":"CVE-2026-112111"},"products":["BIRD"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["nic"]},"summary":"A BGP peer can bypass IPv6 FlowSpec validation to inject unauthorized traffic filtering or redirection rules, affecting network operators using BIRD.","url":"https://insights.sbomify.com/CVE-2026-112112/"}
