CVE-2025-40925 (2025-09-20)

Starch versions 0.14 and earlier generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with a counter, the epoch time, the built-in rand function, the PID, and internal Perl reference addresses. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems.

NAME

Starch::Plugin::ForState - Base role for Starch::State plugins.

SYNOPSIS

package MyPlugin::State;
use Moo;
with 'Starch::Plugin::ForState';
sub foo { print 'bar' }

my $starch = Starch->new(
    plugins => ['MyPlugin::State'],
    ...,
);
$starch->state->foo(); # bar

DESCRIPTION

This role provides no additional functionality to state plugins. All it does is labels a plugin as a state plugin so that Starch knows which class type it applies to.
