Debug Mode in Production

Leaving framework debug features, consoles or verbose diagnostics enabled on production systems.

Definition

Debug modes can expose stack traces, configuration, environment variables and sometimes interactive consoles that allow code execution. Builds and deployment configurations should disable debugging in production, and configuration scanning should verify it.

Example

A production web app runs with its framework debug flag enabled, exposing an interactive error console.

Exam tip

A classic security misconfiguration that can escalate to RCE.
