Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Insecure Randomness: The use of Math.random() in Node.js fallback environments leads to predictable session IDs or connection tokens. Standardizing on cryptographically strong alternatives is critical for transport-layer security.
Information Disclosure: Exposing full iframe DOM elements instead of constrained interfaces allows untrusted calling code to intercept or tamper with low-level cross-origin transport mechanisms.
