It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33596 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-2026-33596/ (Markdown: https://insights.sbomify.com/CVE-2026-33596/index.md)","id":"CVE-2026-33596","markdown":"https://insights.sbomify.com/CVE-2026-33596/index.md","name":"CVE-2026-33596","record":{"aliases":["DEBIAN-CVE-2026-33596","GHSA-jcpx-7c75-g6c9","UBUNTU-CVE-2026-33596"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DNS load balancer","requires_auth":"none","summary":"An attacker can cause query-response mismatches or service disruption in PowerDNS DNSdist by exploiting a stream ID overflow via timed queries.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[{"product":"dnsdist","vendor":"powerdns"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend.","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":"TCP backend stream ID overflow","id":"CVE-2026-33596","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"PRSD detection denial of service","id":"CVE-2026-33597"},"packages":[],"prev":{"headline":"DoQ/DoH3 excessive memory allocation","id":"CVE-2026-33595"},"products":["DNSdist"],"published":"2026-04-22","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in dnsdist","id":"CVE-2017-7557","kev_date_added":null,"published":"2017-08-22"},{"cvss_score":7.5,"headline":"Denial of service via crafted DNSCrypt query","id":"CVE-2026-33593","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.5,"headline":"Off-by-one access when processing crafted UDP responses","id":"CVE-2026-33602","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.5,"headline":"DNS over HTTPS ACL bypass","id":"CVE-2026-24029","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":5.9,"headline":"Out-of-bounds write when rewriting large DNS packets","id":"CVE-2026-27853","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":5.9,"headline":"Other in dnsdist","id":"CVE-2018-14663","kev_date_added":null,"published":"2018-11-26"},{"cvss_score":5.9,"headline":"Denial of service in dnsdist","id":"CVE-2016-7069","kev_date_added":null,"published":"2018-09-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-04-22","vendors":["PowerDNS"]},"summary":"An attacker can cause query-response mismatches or service disruption in PowerDNS DNSdist by exploiting a stream ID overflow via timed queries.","url":"https://insights.sbomify.com/CVE-2026-33596/"}
