Recurring patterns

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

Auth Bypass: Web-accessible endpoints allowing profiling data import/export could lead to unauthorized data exposure and remote exploitation, necessitating their removal in favor of CLI-only interfaces.

Cross-Site Scripting (XSS): Improperly merging CSP directives by retaining 'none' when appending source nonces invalidated CSP headers in browsers, neutralizing client-side protections.

HTTP Response Splitting: Injecting raw, un-normalized exception messages containing line breaks into custom debug response headers permitted HTTP Response Splitting and header injection.
