Recurring patterns

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

SQL Injection: Two separate SQL injection fixes in different components indicate a systemic pattern of unsafe query construction, with user-controlled input concatenated into SQL strings.

Authentication Bypass: Both authentication-related fixes address bypasses through header/cookie handling, showing that authentication state can be overridden or shared improperly across contexts.

Credential Exposure: Credentials were previously placed in query parameters, risking leakage in logs, proxies, and referrer headers; moved to Basic auth to reduce exposure.
