How to fix?

Upgrade org.bouncycastle:bcprov-jdk15to18 to version 1.69 or higher.

Overview

org.bouncycastle:bcprov-jdk15to18 is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Cryptographic Issues via weak key-hash message authentication code (HMAC) that is only 16 bits long which can result in hash collisions, as a result of an error within the BKS version 1 keystore (BKS-V1) files and could lead to an attacker being able to affect the integrity of these files. This vulnerability was introduced following an incomplete fix for CVE-2018-5382.
