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 Caching

SYNOPSIS

use CGI::Session;

$session = new CGI::Session("driver:SomeDriver;id:Static", "my_id", \%attrs);

DESCRIPTION

CGI::Session::ID::Static is used to generate consistent, static session ID's. The only time you would really want to do this is when you need to use CGI::Session for caching information, most likely the results of an expensive database query.

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 cause an error.
