Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Prototype Pollution: Attackers can bypass key validation logic using non-string path components (e.g., arrays or objects) that evade standard string-based blocklists, leading to type confusion and arbitrary prototype modification. Developers must ensure all segment keys are coerced to strings before validation.
Prototype Pollution: Nested path traversal functions failed to block sensitive property keys like '__proto__', 'constructor', and 'prototype', permitting remote attackers to inject properties into the base Object constructor.
