Recurring patterns

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

Reflected XSS: Improperly escaped HTML/script tags in the stringified JSON payload during server-side hydration allows execution of malicious scripts (CVE-2024-24556). Developers must ensure that serialization contexts encode characters like '<' and '>' to prevent execution in client-side HTML contexts.

Prototype Pollution: Recursive merging of AST variables can lead to Prototype Pollution if object properties like '__proto__', 'constructor', or 'prototype' are not explicitly blocked during input resolution.
