## Security Alert: Local File Inclusion Vulnerability Exposed in `app.py` Admin Endpoint
A high-severity Local File Inclusion (LFI) and Path Traversal vulnerability has been identified in a critical administrative endpoint. The flaw, located in the `show_logs` function of `app.py`, allows an authenticated admin user to read sensitive system files far beyond the intended logs directory. By manipulating the `file` parameter, an attacker could potentially access files like `/etc/passwd`, exposing core system configuration and sensitive data.

The vulnerability stems from line 235 in `app.py`, where user-supplied input for the file path is passed directly to the `open()` function without any validation. The code fetches the path via `request.args.get('file', 'app.log')` and immediately attempts to read it, creating a direct path traversal vector. This pattern is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) and is flagged as a high-risk security issue.

This exposure places the entire application server at risk. Unauthorized file reads could lead to credential harvesting, configuration file leaks, and a significant escalation of privileges within the environment. The suggested remediation is to implement strict input validation, such as using an allowlist of permitted filenames or verifying that the resolved absolute path is contained within the intended logs directory using methods like `os.path.abspath` and `os.path.commonprefix`. Immediate patching is required to prevent potential data breaches and system compromise.
