How to Fix CVE-2023-39662

To remediate this vulnerability, upgrade all affected Llama index dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

llama-index fixed: 0.9.14 
pip install llama-index>=0.9.14
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show llama-index

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-39662, inspect your installed packages using pip:

pip show llama-index

Analyze the terminal output to locate any version of Llama index in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.14), your application is affected.

Note: The pip show llama-index command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where 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. In Llama index, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue in llama_index v.0.7.13 and before allows a remote attacker to execute arbitrary code via the `exec` parameter in PandasQueryEngine function.
