How to Fix CVE-2009-2701

To remediate this vulnerability, upgrade all affected ZODB3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ZODB3 fixed: 3.8.3 
pip install ZODB3>=3.8.3
ZODB3 fixed: 3.9.0c2 
pip install ZODB3>=3.9.0c2
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 ZODB3

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2009-2701, inspect your installed packages using pip:

pip show ZODB3

Analyze the terminal output to locate any version of ZODB3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.8.3), your application is affected.

Note: The pip show ZODB3 command checks currently installed packages in your active Python environment.
