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-2026-40208 in the wild and no public exploit code.\n\nAffected product: PowerDNS DNSdist. 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-2026-40208/ (Markdown: https://insights.sbomify.com/CVE-2026-40208/index.md)","id":"CVE-2026-40208","markdown":"https://insights.sbomify.com/CVE-2026-40208/index.md","name":"CVE-2026-40208","record":{"aliases":["DEBIAN-CVE-2026-40208","GHSA-2cpw-vgr2-pw3h","UBUNTU-CVE-2026-40208"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS load balancer","requires_auth":"none","summary":"An attacker can cause denial of service in PowerDNS DNSdist by sending malformed DoH3 GET queries with invalid DATA frames.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-705","name":"Incorrect Control Flow Scoping"}],"description":"An attacker might be able to delay the processing of DoH3 queries by sending DoH3 GET queries with an invalid DATA frame.","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":"Denial of service via DoH3 queries","id":"CVE-2026-40208","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service via IXFR queries","id":"CVE-2026-40209"},"packages":[],"prev":{"headline":"Auth bypass in OX Dovecot CE","id":"CVE-2026-40205"},"products":["DNSdist"],"published":"2026-06-25","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":"2026-06-25","vendors":["PowerDNS"]},"summary":"An attacker can cause denial of service in PowerDNS DNSdist by sending malformed DoH3 GET queries with invalid DATA frames.","url":"https://insights.sbomify.com/CVE-2026-40208/"}
