Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21712 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected from 24.0.0; fixed in 24.14.1, 25.8.2\n- node-min (Bitnami): affected from 24.0.0; fixed in 24.14.1, 25.8.2\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-2026-21712/ (Markdown: https://insights.sbomify.com/CVE-2026-21712/index.md)","id":"CVE-2026-21712","markdown":"https://insights.sbomify.com/CVE-2026-21712/index.md","name":"CVE-2026-21712","record":{"aliases":["ALPINE-CVE-2026-21712","AZL-81101","BELL-CVE-2026-21712","BIT-node-2026-21712","BIT-node-min-2026-21712","GHSA-h8r7-m85c-mjhv","MINI-86c5-mgmp-5m9w","MINI-99px-rrfc-2r47","UBUNTU-CVE-2026-21712"],"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":"low_privilege","summary":"An attacker can crash the Node.js process by calling url.format() with a malformed internationalized domain name, causing a denial of service.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"node.js","vendor":"nodejs"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A flaw in Node.js URL processing causes an assertion failure in native code when `url.format()` is called with a malformed internationalized domain name (IDN) containing invalid characters, crashing the Node.js process.","ecosystems":["Bitnami"],"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 in node","id":"CVE-2026-21712","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"nodejs:node.js","products":["nodejs:node.js"],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Information disclosure in node","id":"CVE-2026-21713"},"packages":[{"ecosystem":"Bitnami","fixed":["24.14.1","25.8.2"],"introduced":["24.0.0","25.0.0"],"last_affected":[],"package":"node","purl":"pkg:bitnami/node","source":"BIT-node-2026-21712"},{"ecosystem":"Bitnami","fixed":["24.14.1","25.8.2"],"introduced":["24.0.0","25.0.0"],"last_affected":[],"package":"node-min","purl":"pkg:bitnami/node-min","source":"BIT-node-min-2026-21712"}],"prev":{"headline":"Security feature bypass in node","id":"CVE-2026-21711"},"products":["node"],"published":"2026-03-30","related":[{"cvss_score":9.8,"headline":"Security feature bypass in Node","id":"CVE-2023-32002","kev_date_added":null,"published":"2023-08-21"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-6303","kev_date_added":null,"published":"2016-09-16"},{"cvss_score":9.1,"headline":"Security feature bypass in Node.js","id":"CVE-2017-15896","kev_date_added":null,"published":"2017-12-11"},{"cvss_score":8.8,"headline":"Server-side request forgery in Node.js","id":"CVE-2018-7160","kev_date_added":null,"published":"2018-05-17"},{"cvss_score":8.1,"headline":"Misconfiguration in Node.js","id":"CVE-2018-12120","kev_date_added":null,"published":"2018-11-28"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21891","kev_date_added":null,"published":"2024-02-20"},{"cvss_score":7.9,"headline":"Path traversal in Node","id":"CVE-2024-21896","kev_date_added":null,"published":"2024-02-20"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2026-05-10","vendors":["nodejs"]},"summary":"An attacker can crash the Node.js process by calling url.format() with a malformed internationalized domain name, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-21712/"}
