How to Fix GHSA-4f84-67cv-qrv3

To remediate this vulnerability, upgrade all affected Dydx v4 client dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dydx-v4-client fixed: 1.1.5 
pip install dydx-v4-client>=1.1.5
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 dydx-v4-client

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-4f84-67cv-qrv3, inspect your installed packages using pip:

pip show dydx-v4-client

Analyze the terminal output to locate any version of Dydx v4 client in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.5), your application is affected.

Note: The pip show dydx-v4-client command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In Dydx v4 client, 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

A PyPI user account compromised by an attacker and was able to upload a malicious version (1.1.5.post1) of the `dydx-v4-client` package. This version contains a highly obfuscated multi-stage loader that ultimately executes malicious code on the host system. While the final payload is not visible because it is tucked away inside 100 layers of encoding, the structural design—specifically the use of recursive decompression followed by an `exec()` call is a definitive indicator of malicious software, likely a "Crypter" or "Dropper" masquerading as a cryptocurrency-related utility with the intent on connecting to hxxps://dydx[.]priceoracle[.]site/py to download and execute further payloads. Users of the `dydx-v4-client` package should immediately uninstall version 1.1.5.post1and revert to the last known good version (1.1.5) or later secure versions once available. Additionally, users should monitor their systems for any unusual activity and consider running security scans to detect any potential compromise.
