Detailsinfo

A vulnerability was found in MervinPraison PraisonAI up to 4.6.77. It has been rated as problematic. Affected by this issue is the function subprocess.Popen of the file src/praisonai/praisonai/deploy/api.py of the component Deploy API. The manipulation of the argument agents_file with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

PraisonAI is a multi-agent teams system. Prior to version 4.6.78, the `deploy/api.py` module generates Python server code by directly interpolating the `agents_file` parameter into an f-string that is then written to a file and executed via `subprocess.Popen()`. An attacker who controls the `agents_file` value (via CLI argument, configuration, or upstream API) can inject arbitrary Python code. Version 4.6.78 patches the issue.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-62176 since 07/13/2026. The exploitation is known to be easy. The attack may be launched remotely. The exploitation requires an enhanced level of successful authentication. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

Upgrading to version 4.6.78 eliminates this vulnerability.
