Remote Code Execution (RCE)

Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to insufficient hostname checks and the use of relative paths to resolve requests. When the debugger is enabled, an attacker can convince a user to enter their own PIN to interact with a domain and subdomain they control, and thereby cause malicious code to be executed.

The demonstrated attack vector requires a number of conditions that render this attack very difficult to achieve, especially if the victim application is running in the recommended configuration of not having the debugger enabled in production.

How to fix Remote Code Execution (RCE)?

Upgrade werkzeug to version 3.0.3 or higher.
