CVE-2026-17356

Summary

IBM API Connect versions 12.1.0.0 through 12.1.1.2 use a hard-coded cryptographic key, allowing a local attacker with access to the system to extract sensitive information by reversing or bypassing encryption mechanisms.

Exploitability

Exploitation requires local access to the affected system and knowledge of where the hard-coded key is stored, making it moderately difficult for an unprivileged attacker but feasible for a compromised local account.

Blast radius

Successful exploitation could expose encrypted credentials, API secrets, or other sensitive data protected by the hard-coded key, potentially enabling further lateral movement or data theft within the environment.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to IBM API Connect 12.1.1.3 or later, where the hard-coded cryptographic key has been replaced with a dynamically generated or securely managed key.
