How to fix?

Upgrade org.webjars.npm:openpgp to version 4.2.0 or higher.

Overview

org.webjars.npm:openpgp is a JavaScript implementation of the OpenPGP protocol.

Affected versions of this package are vulnerable to Improper Authentication. OpenPGP signature subpackets contain information related to a signature (e.g. the creation timestamp). These subpackets may appear in a “hashed” and “unhashed” subpacket container. While the information in the hashed subpackets is signed, the unhashed subpackets are not cryptographically protected.

An attacker could arbitrarily modify the contents of e.g. a key certification signature or revocation signature. As a result, the attacker could e.g. convince a victim to use an obsolete key for encryption.
