The CVE-2025-XXXX vulnerability in smolagents v1.14.0 allows attackers to bypass Python sandboxing in the `local_python_executor.py` module. The flaw occurs due to insufficient validation of whitelisted modules and functions, enabling malicious actors to chain allowed operations into arbitrary code execution. Despite static and dynamic checks, attackers can manipulate the execution context to escape the restricted environment, leading to Remote Code Execution (RCE). This compromises the host system by abusing legitimate Python features, such as `__import__` or built-in overrides, to execute unauthorized commands.
DailyCVE Form:
Platform: smolagents
Version: 1.14.0

malicious_code = "<strong>import</strong>('os').system('id')"
executor.execute(malicious_code)
Mitigation command
pip install smolagents==1.17.0
