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 poetry

How to Check if You Are Affected

pip show poetry

Analyze the terminal output to locate any version of Poetry in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.9), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-426: Untrusted Search Path, where the product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control. In Poetry, 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

Poetry prior to v1.1.9 was discovered to contain an untrusted search path which causes the application to behave in unexpected ways when users execute Poetry commands in a directory containing malicious content. This vulnerability occurs when the application is ran on Windows OS.
