The PostgreSQL adapter in Active Record is vulnerable to regular expression denial of service (ReDoS). An attacker can send a carefully crafted input to cause the input validation in the money type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input.
