CVE-2026-2401

# Proof of Concept for CVE-2026-2401 # This script simulates the execution of a file that triggers sensitive logging. import os def simulate_malicious_execution(): # Simulate the payload execution by a Web Admin print("[*] Simulating execution of malicious file...") # In a real scenario, this specific action would trigger the app logging sensitive info sensitive_info = "CONFIDENTIAL_ADMIN_TOKEN=XYZ-123-ADMIN" # Simulate writing to a log file log_file = "/var/log/application/sensitive.log" print(f"[*] Application might log sensitive data to: {log_file}") print(f" Content: {sensitive_info}") # Check if log exists (Mock) # if os.path.exists(log_file): # with open(log_file, 'r') as f: # print(f.read()) if __name__ == "__main__": simulate_malicious_execution()
