CVE-2022-44566

Published: 9 February 2023

A denial of service vulnerability present in ActiveRecord's PostgreSQL adapter <7.0.4.1 and <6.1.7.1. When a value outside the range for a 64bit signed integer is provided to the PostgreSQL connection adapter, it will treat the target column type as numeric. Comparing integer values against numeric values can result in a slow sequential scan resulting in potential Denial of Service.
