GHSA-8hc4-xxm3-5ppp
Active Record subject to Regular Expression Denial-of-Service (ReDoS)
Quick fix
GHSA-8hc4-xxm3-5ppp — activerecord: upgrade to the fixed version with the command below.
bundle update activerecordDetails
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.
