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-2026-77119 in the wild and no public exploit code.\n\nAffected product: ISC BIND 9. 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-2026-77119/ (Markdown: https://insights.sbomify.com/CVE-2026-77119/index.md)","id":"CVE-2026-77119","markdown":"https://insights.sbomify.com/CVE-2026-77119/index.md","name":"CVE-2026-77119","record":{"aliases":["ALPINE-CVE-2026-77119","AZL-103341","BELL-CVE-2026-77119","DEBIAN-CVE-2026-77119","ECHO-13f4-9e5a-3fae","GHSA-r3pf-h3x3-rv3w","MINI-758m-9xx2-whc5","MINI-j564-cgcm-g489","MINI-m5m7-9c4m-vj2j","OESA-2026-4607","OESA-2026-4608","UBUNTU-CVE-2026-77119"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS server software","requires_auth":"none","summary":"Attackers can bypass DNSSEC validation by using unrelated cached NSEC3 records to forge unsigned answers, affecting BIND 9 users.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"A validly signed NSEC3 from an unrelated sibling zone may be accepted as an insecurity proof, downgrading a secure delegation and letting a forged unsigned answer through.\nThis issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"NSEC3 insecure-referral proof can use unrelated cached NSEC3 RRsets","id":"CVE-2026-77119","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in PowerLogic T300","id":"CVE-2026-77120"},"packages":[],"prev":{"headline":"Out-of-bounds write in GraphicsMagick PCD decoder","id":"CVE-2026-77118"},"products":["BIND 9"],"published":"2026-09-16","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":"2026-09-17","vendors":["ISC"]},"summary":"Attackers can bypass DNSSEC validation by using unrelated cached NSEC3 records to forge unsigned answers, affecting BIND 9 users.","url":"https://insights.sbomify.com/CVE-2026-77119/"}
