CVE-2026-18175Network attack vector

Database transaction manipulation via improper authorization

Published Sep 4, 2026 · Updated Sep 4, 2026

Improper authorization in IBM operating system releases 7.3 through 7.6 allows remote attackers to manipulate database transactions through DDM. The DDM target dispatcher processes transaction operations without enforcing the required authorization, although IBM has not disclosed the specific check or request field involved. No credentials or user interaction are required, but exploitation has high complexity and can alter database transaction integrity.
