Foundation Agents MetaGPT actionoutput_str_to_mapping Code Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foundation Agents MetaGPT. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the actionoutput_str_to_mapping function. The issue results from the lack of proper validation of a user-supplied string before using it to execute Python code. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-28124.
AnalysisAI
MetaGPT has a code injection vulnerability in actionoutput_str_to_mapping (EPSS 2.6%) allowing remote attackers to execute arbitrary code through crafted AI agent output processing.
Technical ContextAI
The actionoutput_str_to_mapping function in MetaGPT has a CWE-94 code injection vulnerability that processes agent output strings using eval-like constructs, allowing injected code to execute.
RemediationAI
Update MetaGPT. Replace eval-based parsing with safe JSON parsing. Never evaluate LLM outputs as code.
