How to Fix CVE-2024-47532

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

RestrictedPython fixed: 7.3 
pip install RestrictedPython>=7.3
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 RestrictedPython

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-47532, inspect your installed packages using pip:

pip show RestrictedPython

Analyze the terminal output to locate any version of RestrictedPython in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In RestrictedPython, 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

### Impact A user can gain access to protected (and potentially sensible) information indirectly via `AttributeError.obj` and the `string` module. ### Patches The problem will be fixed in version 7.3. ### Workarounds If the application does not require access to the module `string`, it can remove it from `RestrictedPython.Utilities.utility_builtins` or otherwise do not make it available in the restricted execution environment.
