How to Fix CVE-2024-34528

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

wordops fixed: 3.21.0 
pip install wordops>=3.21.0
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 wordops

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-34528, inspect your installed packages using pip:

pip show wordops

Analyze the terminal output to locate any version of Wordops in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.21.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Wordops, 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

WordOps through 3.20.0 has a `wo/cli/plugins/stack_pref.py` TOCTOU race condition because the `conf_path` `os.open` does not use a mode parameter during file creation.
