Detailsinfo

A vulnerability classified as very critical has been found in MervinPraison PraisonAI up to 1.6.77. Affected is the function CodeAgent._execute_python of the component AST Validation. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74.
