CVE-2024-31895Network attack vector

Authenticated information disclosure via expired access tokens

Published May 22, 2024 · Updated Aug 2, 2024

Information disclosure in IBM App Connect Enterprise 12.0.1.0 through 12.0.12.1 allows remote authenticated users to read user data. An affected Discovery Connector node accepts an expired access token for a user-information request instead of rejecting the stale credential. Access requires a previously issued token and exposes connector-retrieved user information without reported data modification or service interruption.
