Recurring patterns

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

Reflected XSS: HTML parsing and DOM manipulation helper functions (such as htmlPrefilter) are highly susceptible to bypasses in self-closing tag processing and sanitization logic, letting attackers inject and execute arbitrary scripts through standard DOM methods.
Prototype Pollution: The deep-copy logic in object extend utilities historically failed to validate and block modifications targeting the '__proto__' key, enabling remote attackers to pollute the global Object prototype and achieve remote code execution or application denial of service.
