How to fix?

Upgrade Chainguard eco-python-curl to version 8.21.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream eco-python-curl package and not the eco-python-curl package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup.

An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA material for a later transfer.
