CVE-2023-29256Network attack vector

Authenticated data disclosure through federation privileges

Published Jul 9, 2023 · Updated Feb 13, 2025

Information disclosure in IBM Db2 10.5, 11.1, and 11.5 allows remote authenticated users to read data through federation features. IBM identifies improper privilege management in certain federation features but withholds the affected function and authorization error. A valid low-privilege account and an enabled federation configuration are required; the issue affects confidentiality without reported data modification or service interruption.
