CVE-2026-17467Network attack vector

Sensitive information disclosure via deprecated cryptographic protocols

Published Sep 14, 2026 · Updated Sep 14, 2026

Weak cryptography in IBM Cloud Pak for Data System 3.0.5.2 allows remote attackers to obtain sensitive information over the network. The Yosemite 1.0 system uses weak or deprecated cryptographic protocols for protected communications, but IBM has not identified the protocols or endpoints. Exploitation requires network access to a service that negotiates an affected protocol, exposing protected data and potentially undermining its integrity.
