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-2026-0396/ (Markdown: https://insights.sbomify.com/CVE-2026-0396/index.md)","id":"CVE-2026-0396","markdown":"https://insights.sbomify.com/CVE-2026-0396/index.md","name":"CVE-2026-0396","record":{"aliases":["DEBIAN-CVE-2026-0396","GHSA-c6vq-q4cf-9cgj","UBUNTU-CVE-2026-0396"],"analysis":null,"analysis_generated_by":null,"assigner":"OX","cpe":[{"product":"dnsdist","vendor":"powerdns"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"An attacker might be able to inject HTML content into the internal web dashboard by sending crafted DNS queries to a DNSdist instance where domain-based dynamic rules have been enabled via either DynBlockRulesGroup:setSuffixMatchRule or DynBlockRulesGroup:setSuffixMatchRuleFFI.","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":"HTML injection in the web dashboard","id":"CVE-2026-0396","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure via CORS misconfiguration","id":"CVE-2026-0397"},"packages":[],"prev":{"headline":"Path traversal in OX Dovecot Pro","id":"CVE-2026-0394"},"products":["DNSdist"],"published":"2026-03-31","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":"2026-03-31","vendors":["PowerDNS"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-0396/"}
