Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Prototype Pollution: Recursive assignment of keys without validating against special properties like '__proto__', 'constructor', or 'prototype' allows attackers to pollute the global Object prototype, leading to potential Denial of Service or Remote Code Execution depending on the application context.
Prototype Pollution: Merging objects recursively without verifying property ownership enables prototype pollution if properties from the source object are merged blindly into the target.
