CVE-2024-23752

Arbitrary Python code execution in PandasAI (through 1.5.17) via GenerateSDFPipeline

• CVSS 9.8
• CWE-862
• Input Validation and Sanitization
• Remote

GenerateSDFPipeline in synthetic_dataframe in PandasAI (aka pandas-ai) through 1.5.17 allows attackers to trigger the generation of arbitrary Python code that is executed by SDFCodeExecutor. An attacker can create a dataframe that provides an English language specification of this Python code. NOTE: the vendor previously attempted to restrict code execution in response to a separate issue, CVE-2023-39660.
