CVE-2022-44566: Activerecord Project Activerecord

High severity, CVSS 7.5. EPSS: 1.3% chance of exploitation in the next 30 days.

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.

Affected products

• Activerecord Project Activerecord: before 6.1.7.1 (fixed in 6.1.7.1); from 7.0.0, before 7.0.4.1 (fixed in 7.0.4.1)
