{"id":"ALPINE-CVE-2021-44532","details":"Node.js \u003c 12.22.9, \u003c 14.18.3, \u003c 16.13.2, and \u003c 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.","modified":"2026-10-27T08:33:27.674798731Z","published":"2022-02-24T19:15:09.360Z","upstream":["CVE-2021-44532"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-44532"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.22.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.19.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"14.19.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.13.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs-current","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/nodejs-current?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2021-44532.json"}},{"package":{"name":"nodejs-current","ecosystem":"Alpine:v3.16","
