Hi, The following vulnerability was published for libcgi-session-perl. CVE-2026-56016[0]: | CGI::Session::ID::md5 versions before 4.49 for Perl generate | predictable session ids from low-entropy sources. The generate_id | method builds the session id from a MD5 digest of the process id, | the epoch time, and the built-in rand() function. All three are | predictable, low-entropy sources: the PID is drawn from a small | range, the epoch time can be guessed or read from the HTTP Date | header, and Perl's rand() is unsuitable for security purposes | because it is predictable and reversible. An attacker who predicts | a session id can impersonate the corresponding session and bypass | authentication. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
