Recurring patterns

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

Auth Bypass: Unprivileged extensions could execute arbitrary internal commands. Prevention requires enforcing robust permission checks against extension metadata at the command invocation boundary.

Denial of Service: Parsing syntax highlighting on excessively long lines triggers extreme CPU usage. Standard mitigations must completely skip tokenization when line lengths exceed safe boundaries instead of processing truncated strings.

Cross-Site Scripting (XSS): Relying on outdated configuration options of the parser allows bypasses of rendering safety checks. This must be prevented by passing raw output through a dedicated sanitization library before UI injection.
