Vulnerability Title
openssl_encrypt before 1.4.0 TOTP Rate Limiter Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
openssl_encrypt versions before 1.4.0 use an in-memory rate limiter for TOTP brute-force protection that is not shared across workers and is lost on server restart. Attackers can distribute authentication attempts across multiple server instances or retry immediately after a restart to bypass rate limiting protections.
