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.

Some Hikvision Hybrid SAN products were vulnerable to multiple remote code execution (command injection) vulnerabilities, including reflected cross site scripting, Ruby code injection, classic and blind SQL injection resulting in remote code execution that allows an adversary to execute arbitrary operating system commands and more. However, an adversary must be on the same network to leverage this vulnerability to execute arbitrary commands.

Security vulnerability was one of Meta’s top bugs of 2022
