CVE-2026-6719: CWE-330 Use of Insufficiently Random Values in IBM Concert

CVE-2026-6719 describes a vulnerability in IBM Concert versions 1.0 through 3.0.0 where weaker than expected cryptographic algorithms are used. This weakness could enable an attacker to decrypt highly sensitive information by exploiting insufficient randomness in cryptographic processes, classified under CWE-330. The vulnerability has a CVSS 3.1 base score of 7.5, indicating a high severity with network attack vector and no required privileges or user interaction. There is no information about available patches or fixes, and no known exploits in the wild have been reported.

An attacker can potentially decrypt highly sensitive information due to the use of insufficiently random values in cryptographic algorithms within IBM Concert 1.0 through 3.0.0. This compromises confidentiality but does not affect integrity or availability. The vulnerability can be exploited remotely without authentication or user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or fix information is provided, users should monitor IBM's official channels for updates. Until a fix is available, consider limiting exposure of affected versions to untrusted networks.
