CVE-2026-15266

Summary

IBM Concert versions 1.0 through 3.0.1.1 contain components vulnerable to command injection (CWE-78), allowing unauthenticated remote attackers to execute arbitrary system commands on the host. This is a critical flaw due to the CVSS 9.8 score indicating full confidentiality, integrity, and availability impact.

Exploitability

Exploitation requires no authentication or user interaction and can be performed remotely over the network with low technical complexity, assuming the vulnerable component is exposed.

Blast radius

Successful exploitation would allow attackers to fully compromise the affected system, including stealing sensitive data, installing backdoors, or pivoting to other systems within the network.

Detection

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

Prioritized remediation

Upgrade IBM Concert to version 3.0.1.2 or later, as this is the first fixed release addressing CVE-2026-15266.
