phpseclib versions from 0.1.1 up to but not including 1.0.30, 2.0.55, and 3.0.54 contain a server-side request forgery (SSRF) vulnerability. The X509::validateSignature() function reads a URL from the Authority Information Access extension of an untrusted X.509 certificate and connects to it by default, allowing an attacker to control the destination of the connection. This can lead to unauthorized internal network access. The vulnerability is fixed in versions 1.0.30, 2.0.55, and 3.0.54.
