io.undertow:undertow-core is vulnerable to Improper Certificate Validation. The vulnerability is due to missing certificate validation in the Http2ClientProvider class to check if the identity is presented by the server certificate in HTTPS connections. If the ENDPOINT_IDENTIFICATION_ALGORITHM is not set, it allows connections without verifying the server’s identity which results in a certificate bypass.
