How to Fix CVE-2023-47204

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

transmute-core fixed: 1.13.5 
pip install transmute-core>=1.13.5
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 transmute-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-47204, inspect your installed packages using pip:

pip show transmute-core

Analyze the terminal output to locate any version of Transmute core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.5), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Transmute core, 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

Unsafe YAML deserialization in yaml.Loader in transmute-core before 1.13.5 allows attackers to execute arbitrary Python code.
