TL;DR

Affected versions of this package are affected by improper handling of Online Certificate Status Protocol (OCSP) requests for intermediate certificates in a TLS 1.3 connection, particularly when OCSP stapling is not enabled. It could lead to a bypass when validating these intermediate certificates. As a result, this oversight may expose the connection to potential security risks, such as replay attacks.
