Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Prototype Pollution: Attackers can bypass security checks or trigger unexpected behavior by crafting DOM attribute names that match built-in Object prototype properties (e.g., 'toString' or 'constructor'), which are then incorrectly identified as present on the element.
