GoogleOSV:GHSA-8HC4-XXM3-5PPPActive Record subject to Regular Expression Denial-of-Service (ReDoS)
EPSS
Percentile
78.6%
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.
