An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78301 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-2026-78301/ (Markdown: https://insights.sbomify.com/CVE-2026-78301/index.md)","id":"CVE-2026-78301","markdown":"https://insights.sbomify.com/CVE-2026-78301/index.md","name":"CVE-2026-78301","record":{"aliases":["ALPINE-CVE-2026-78301","AZL-103332","BELL-CVE-2026-78301","CLSA-2026-1792630839","DEBIAN-CVE-2026-78301","ECHO-1eea-cbca-9338","GHSA-wx7p-v693-68jh","MINI-6q92-pfj3-j5fj","MINI-ff9g-4jrh-5rh2","MINI-fgh3-7wxf-r656","UBUNTU-CVE-2026-78301"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BIND DNS server","requires_auth":"high_privilege","summary":"Attackers can inject malformed zones to create fake zone cuts, causing BIND to cache incorrect data and bypass authoritative checks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-349","name":"Acceptance of Extraneous Untrusted Data With Trusted Data"}],"description":"A malformed zone may contain an NS or DNAME node above its origin, which `named` treats as a zone cut. If an attacker inserts a malformed zone into a BIND authoritative server (e.g., via zone transfer), queries for names inside the configured zone then lose authoritative status and return an out-of-zone delegation. On a server that also provides recursion BIND can follow this locally sourced cut and cache attacker-supplied data, affecting names outside the configured zone. This situation persists as long as the malformed zone remains in the zone database.\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":"Out-of-zone database nodes can become authoritative zone cuts","id":"CVE-2026-78301","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in SP Property extension for Joomla","id":"CVE-2026-78302"},"packages":[],"prev":{"headline":"Path traversal in Eclipse Embedded CDT (C/C++ Development Tools)","id":"CVE-2026-78299"},"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 inject malformed zones to create fake zone cuts, causing BIND to cache incorrect data and bypass authoritative checks.","url":"https://insights.sbomify.com/CVE-2026-78301/"}
