Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable.","state":0,"publishedAt":"2022-02-24T18:27:02+00:00","modifiedAt":"2026-10-08T21:24:19.986+00:00","affected":[{"ecosystem":"Vendor product","name":"Node","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Node\",\n                    \"vendor\": \"NodeJS\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"4.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"4.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"5.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"5.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"6.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"6.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"7.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"7.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"8.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"8.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"9.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"9.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"10.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"10.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"11.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"11.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"12.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"12.22.9\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"13.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"13.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"14.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"14.18.3\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"15.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"15.*\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"16.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"16.13.2\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"version\": \"17.0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"17.3.1\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://hackerone.com/reports/1429694","https://nodejs.org/en/blog/vulnerability/jan-2022-security-releases/","https://www.oracle.com/security-alerts/cpuapr2022.html","https://security.netapp.com/advisory/ntap-20220325-0007/","https://www.debian.org/security/2022/dsa-5170","https://www.oracle.com/security-alerts/cpujul2022.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2021-44533","license":"CVE Program Terms of Use","key":"cve-program:CVE-2021-44533","identifiers":["CVE-2021-44533"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog;
