CVE-2025-36365Network attack vector

Authenticated command execution via user-controlled storage key

Published Jan 30, 2026 · Updated Jan 30, 2026

Authorization bypass in IBM Db2 Server 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 allows remote authenticated users to execute commands. With cataloged remote storage aliases enabled, Db2 accepts a user-controlled key without enforcing the required authorization check; IBM has withheld the affected function and reproduction steps. The issue is reachable over the network with low privileges only on Linux servers using that specific object-storage configuration, and it permits unauthorized command execution with confidentiality and integrity impact.
