{"id":"AZL-8840","summary":"CVE-2021-44531 affecting package nodejs for versions less than 16.14.0-1","details":"Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js \u003c 12.22.9, \u003c 14.18.3, \u003c 16.13.2, and \u003c 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.","modified":"2026-04-01T05:23:35.760370Z","published":"2022-02-24T19:15:09Z","upstream":["CVE-2021-44531"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-44531"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/nodejs"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.14.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-8840.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
