EspoCRM 5.6.4 is vulnerable to user password hash enumeration. A malicious authenticated attacker can brute-force a user password hash by 1 symbol at a time using specially crafted api/v1/User?filterList filters.
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.
