Reflected XSS: Dominant vulnerability class with 65 fixes, indicating pervasive lack of output encoding across many contexts (HTML, JS, attributes).
SQL Injection: 24 fixes, many critical, centered on privilege management and query building. Recurring issue: improper escaping (escapeString vs quoteString) and wildcard handling.
