Possible DoS Vulnerability in Active Record PostgreSQL adapter
There is a possible DoS vulnerability in the PostgreSQL adapter in Active
Record. This vulnerability has been assigned the CVE identifier CVE-2021-22880.
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.
Workarounds
In the case a patch can't be applied, the following monkey patch can be used
in an initializer:
Carefully crafted input can cause a DoS via the regular expressions used
for validating the money format in the PostgreSQL adapter. This patch
fixes the regexp.
