  "details": "Apache::Session::Generate::SHA256 versions before 1.3.19 for Perl create insecure session ids.  Apache::Session::Generate::SHA256 generated session ids insecurely. The default session id generator returns a SHA-256 hash of the built-in rand() function, the epoch time, and the PID, that is hashed again. These are predictable, low-entropy sources. Predicable session ids could allow an attacker to gain access to systems.  Note that version 1.3.19 has a fallback without warning to use insecure session generation method if the call to Crypt::URandom::urandom fails. However, this is unlikely as Crypt::URandom is a hardcoded requirement of the module.  This issue is similar to CVE-2025-40931 for Apache::Session::Generate::MD5.",
