CVE-2022-30935: b2evolution

Critical severity, CVSS 9.1. EPSS: 1.4% chance of exploitation in the next 30 days.

An authorization bypass in b2evolution allows remote, unauthenticated attackers to predict password reset tokens for any user through the use of a bad randomness function. This allows the attacker to get valid sessions for arbitrary users, and optionally reset their password. Tested and confirmed in a default installation of version 7.2.3. Earlier versions are affected, possibly earlier major versions as well.
