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-2026-10723 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-2026-10723/ (Markdown: https://insights.sbomify.com/CVE-2026-10723/index.md)","id":"CVE-2026-10723","markdown":"https://insights.sbomify.com/CVE-2026-10723/index.md","name":"CVE-2026-10723","record":{"aliases":["ALPINE-CVE-2026-10723","AZL-93120","BELL-CVE-2026-10723","DEBIAN-CVE-2026-10723","ECHO-ed2d-c1b0-5e9e","GHSA-4fw4-hmvf-4www","MINI-h959-8whg-8c2p","MINI-jfjm-xxfg-945w","MINI-p9f7-r7hx-cqfc","UBUNTU-CVE-2026-10723"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS server software","requires_auth":"none","summary":"Attackers can forge authenticated NXDOMAIN responses by exploiting incorrect NSEC3 record validation in BIND, potentially misleading DNS clients.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses.\nThis issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-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":"Incorrect acceptance of NSEC3 records","id":"CVE-2026-10723","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Reviews Feed \u003c 2.6.5 - Unauthenticated Stored Arbitrary Shortcode Execution via Google Reviews","id":"CVE-2026-10724"},"packages":[],"prev":{"headline":"cilium ebpf LoadCollectionSpec/LoadCollectionSpecFromReader btf.go loadRawSpec integer overflow","id":"CVE-2026-10722"},"products":["BIND 9"],"published":"2026-07-22","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":"2026-07-22","vendors":["ISC"]},"summary":"Attackers can forge authenticated NXDOMAIN responses by exploiting incorrect NSEC3 record validation in BIND, potentially misleading DNS clients.","url":"https://insights.sbomify.com/CVE-2026-10723/"}
