CVE-2025-40933: Kgoldov Apache::authany

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Apache::AuthAny::Cookie v0.201 or earlier for Perl generates session ids insecurely. Session ids are generated using an MD5 hash of the epoch time and a call to the built-in rand function. 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.

Affected products

• Kgoldov Apache::authany: from 0.19, up to and including 0.201
