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.","published":"2022-02-24T19:15:09.000Z","lastModified":"2026-06-17T04:12:32.000Z","status":"Modified","sourceIdentifier":"support@hackerone.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-296","CWE-295"],"affected":["nodejs/node.js","oracle/graalvm","oracle/mysql cluster","oracle/mysql connectors","oracle/mysql enterprise monitor","oracle/mysql server","oracle/mysql workbench","oracle/peoplesoft enterprise peopletools","debian/debian linux"],"epss":{"score":0.10364,"percentile":0.95727,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 10.4%, higher than 96% of all known CVEs.
