CVE-2026-17045Network attack vector

Authenticated data access and operations via capture-replay

Published Aug 13, 2026 · Updated Aug 13, 2026

Improper session management in IBM's Power OS 7.3 through 7.6 allows remote authenticated users to access data and perform unauthorized operations. The flaw is in Digital Certificate Manager, but IBM has not disclosed the affected session artifact, handler, or operation that permits capture-replay. Network access and low privileges are required; exploitation compromises confidentiality and integrity without a reported availability impact.
