IBM i 7.3-7.6 Hardcoded Crypto Constants Remote Disclosure of Sensitive Data
CVE-2026-16693 Published on September 4, 2026
IBM i is Affected By Cryptographic Algorithm Weakness in DCM []
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to the use of hardcoded cryptographic constants to obfuscate encryption keys.
Vulnerability Analysis
CVE-2026-16693 can be exploited with local system access, and requires user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Use of a Broken or Risky Cryptographic Algorithm
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information. The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.
