CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Object Cache 4 everyone the fix is 2.3.3: builds <= 2.3.2 are affected, anything from 2.3.3 onward is not.

Remediation
