CVE-2025-14456Network attack vector

Sensitive-data decryption via weak cryptographic algorithms

Published Mar 3, 2026 · Updated Mar 3, 2026

Risky cryptography in IBM MQ Appliance 9.4.4.0 through 9.4.4.1 allows remote attackers to decrypt highly sensitive data. IBM has not disclosed which cryptographic algorithm, protocol, key material, or appliance component performs the weaker-than-expected operation. Exploitation requires network access and high-complexity conditions, and the reported consequence excludes data modification and service interruption.
