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-2026-58042 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1, 26.5.1\n- node-min (Bitnami): affected all versions; fixed in 22.23.2, 24.18.1, 26.5.1\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-2026-58042/ (Markdown: https://insights.sbomify.com/CVE-2026-58042/index.md)","id":"CVE-2026-58042","markdown":"https://insights.sbomify.com/CVE-2026-58042/index.md","name":"CVE-2026-58042","record":{"aliases":["ALPINE-CVE-2026-58042","BELL-CVE-2026-58042","BIT-node-2026-58042","BIT-node-min-2026-58042","CLEANSTART-2026-AN10958","DEBIAN-CVE-2026-58042","ECHO-6029-e204-9f0d","GHSA-pgf6-87r4-94vm","MINI-2fc5-5w56-2x5w","MINI-2qjg-2867-5rm4","MINI-4p88-72gp-8wwm","MINI-7gff-j726-328g","MINI-c5pj-h636-gxh7","MINI-f247-c3cv-q638","MINI-jgfp-8733-m3vh","MINI-q7w5-2xm6-cp7g","UBUNTU-CVE-2026-58042"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js runtime","requires_auth":"none","summary":"An attacker can cause a Node.js process to abort by sending a DNS response with over 256 A records, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A flaw in Node.js can cause dns.resolveAny() Aborts the Node.js Process When a DNS Response Contains More Than 256 A Records.\r\n\r\nRepeated triggering of this condition can lead to denial of service.\r\n\r\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-23T23:45:07Z","kind":"github_poc","ref":"https://github.com/CompleteTech-Security/node-cve-2026-58042-check","stars":0,"title":"Offline Node.js evidence checker for CVE-2026-58042: DNS resolveAny process abort.
