Overview
Affected versions of this package are vulnerable to Improper Certificate Validation due to incomplete validation in the X.509 certificate verification process. An attacker can cause unauthorized certificates to be accepted as valid by controlling a subordinate Certificate Authority and exploiting the insufficient cross-domain Public Key Infrastructure restrictions, potentially enabling impersonation of trusted domains and interception of secure communications.
