CVE-2026-81859

Local information disclosure via undisclosed weak cryptography

Published Sep 4, 2026 · Updated Sep 4, 2026

Weak cryptography in IBM Enterprise Records in IBM Cloud Pak for Business Automation allows local users to obtain sensitive information. IBM identifies the component and weakness class but does not disclose the algorithm, protected data, cryptographic operation, or code locus. Exploitation requires local access, needs no application privileges or user interaction, and affects confidentiality without reported data modification or service interruption.
