Last modified
CVE-2023-52892 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
