AI-suggested

A fix is available in CallBackery version 0.62.0 and later. Users should upgrade to version 0.62.0 or newer to mitigate this vulnerability. No other mitigation or workaround is indicated in the available data.

Description

CallBackery versions before 0.62.0 for Perl have a vulnerability in the session cookie signing mechanism. The signing secret is generated using the built-in rand() function seeded with 32 bits, resulting in a limited secret space of at most 2^32 values. An attacker who obtains a single signed session cookie can perform an offline brute-force attack to recover the secret and then forge session cookies for any user, including administrators.
