@app.route("/api/get-browser-snapshot", methods=["GET"])

# Security Update!!
@app.route("/api/get-browser-snapshot", methods=["GET"])
@route_logger(logger)
def browser_snapshot():
    # TO-DO: Update allowed paths
    allowed_paths = ["/path/to/snapshots/file1.png", "/path/to/snapshots/file2.jpg"]
    snapshot_path = request.args.get("snapshot_path")
    if snapshot_path in allowed_paths:
        return send_file(snapshot_path, as_attachment=True)
    else:
        return jsonify({"code":403,"reason": "Forbidden Path"}), 403

Security Vulnerability Fix:

• Path Traversal Prevention:
  • Implemented stricter validation for file paths to prevent directory traversal attacks.
  • Ensured that only files within the allowed directory can be accessed.
  • Added checks to sanitize and validate the snapshot_path parameter.

I actually comment out for you guys probably you should give /tmp folder only bc attacker should not be able to access another directories.
