Description

The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can 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.

Affected configurations

• rubyonrails rails (>= 4.2.0 < 5.2.4.5) • rubyonrails rails (>= 6.0.0 < 6.0.3.5) • rubyonrails rails (>= 6.1.0 < 6.1.2.1) • fedoraproject fedora 32 • fedoraproject fedora 33
