CVE-2026-56016 (2026-07-01)

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.

NAME

CGI::Session::MD5 - provides default generate_id() method for CGI::Session

SYNOPSIS

my $session_id = $self->generate_id()

DESCRIPTION

You normaly do not have to use it. It will be called by CGI::Session whenever a new session identifier is required. But if you want, you can override the default generate_id(). ( see developer section of the CGI::Session manual)
