Name of the Vulnerable Software and Affected Versions PyO3 versions 0.23.0 through 0.23.2

Description The issue arises from a regression in the PYO3 CONFIG FILE environment variable, which is used to configure builds. This regression causes PyO3 to fail to reconfigure and recompile when the environment variable is changed. As a result, when using tools like maturin to build for multiple versions in a single build, Python wheels may be compiled against the wrong Python API version. This can lead to highly unstable wheels that will crash the Python interpreter in unpredictable ways.

Recommendations For PyO3 versions 0.23.0 through 0.23.2, update to PyO3 0.23.3 and rebuild to prevent the creation of unstable wheels.
