CVE-2006-1279 (2006-03-19)

CGI::Session 4.03-1 allows local users to overwrite arbitrary files via a symlink attack on temporary files used by (1) Driver::File, (2) Driver::db_file, and possibly (3) Driver::sqlite.

possible SQL injection attack

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::ID::static - CGI::Session ID Driver for generating static IDs

SYNOPSIS

use CGI::Session;
$session = new CGI::Session("id:static", $ENV{REMOTE_ADDR});

DESCRIPTION

CGI::Session::ID::static is used to generate consistent, static session ID's. In other words, you tell CGI::Session ID you want to use, and it will honor it.

Unlike the other ID drivers, this one requires that you provide an ID when creating the session object; if you pass it an undefined value, it will croak.
