How to Fix GHSA-f3q4-ggfp-jv34

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

Adyen fixed: 7.1.0 
pip install Adyen>=7.1.0
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 Adyen

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-f3q4-ggfp-jv34, inspect your installed packages using pip:

pip show Adyen

Analyze the terminal output to locate any version of Adyen in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.1.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for data. In Adyen, 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

Adyen has utility methods for validating notification HMAC signatures. The `is_valid_hmac` and `is_valid_hmac_notification` methods are vulnerable to a timing attack, you should compare the hash of the HMACs instead.
