CWE	CWE-807: Reliance on Untrusted Inputs in a Security Decision
Confidence Level	High
Impact Level	Low
Likelihood Level	Low

Description

Relying on std::env::args_os() for security decisions is unsafe because command-line arguments can be modified or spoofed by users. The first argument, often assumed to be the executable path, can contain arbitrary content and should not be trusted.

Impact

If your application uses args_os for authentication, authorization, or other security checks, attackers could manipulate process arguments to bypass protections or mislead the application, potentially leading to unauthorized access or incorrect behavior.
