What is CVE-2017-12974?

The Nimbus JOSE+JWT library prior to version 4.36 contains a flaw in ECKey construction, where it fails to validate the public x and y coordinates against the specified curve. This oversight may enable attackers to perform an Invalid Curve Attack, specifically in contexts where the Java Cryptography Extension (JCE) provider does not implement essential curve validation. It is crucial for users to update their systems to mitigate the risks associated with this vulnerability.
