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-2026-52690 in the wild and no public exploit code.\n\nAffected product: PowerDNS Recursor. 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-2026-52690/ (Markdown: https://insights.sbomify.com/CVE-2026-52690/index.md)","id":"CVE-2026-52690","markdown":"https://insights.sbomify.com/CVE-2026-52690/index.md","name":"CVE-2026-52690","record":{"aliases":["DEBIAN-CVE-2026-52690","GHSA-c2h5-7f6m-jqmp","UBUNTU-CVE-2026-52690"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerDNS Recursor","requires_auth":"none","summary":"Attackers can spoof replies to mark authoritative servers as non-EDNS capable, causing DNSSEC validation failures in PowerDNS Recursor.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Spoofing replies to Recursor might mark an IP of an authoritative server as not supporting EDNS, causing valdiation of DNSSEC records served by that server to fail.","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":"Spoofed answers can mark an authoritative non-EDNS capable","id":"CVE-2026-52690","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Griffin Hive Metastore Module: SQL Injection Vulnerability in Hive Metastore Module","id":"CVE-2026-52691"},"packages":[],"prev":{"headline":"RRSIGs with too few labels can lead to bypass of DNSSEC wildcard validation","id":"CVE-2026-52688"},"products":["Recursor"],"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":"Attackers can spoof replies to mark authoritative servers as non-EDNS capable, causing DNSSEC validation failures in PowerDNS Recursor.","url":"https://insights.sbomify.com/CVE-2026-52690/"}
