CVE-2026-6930 IBM CVE debrief

Who should care

Defenders responsible for IBM Concert deployments should assess exposure to potential decryption of highly sensitive information and verify the use of weak cryptographic algorithms.

Why it matters

IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms, which could allow an attacker to decrypt highly sensitive information. Defenders should prioritize verifying the use of weak cryptographic algorithms and assess exposure to potential decryption.

• Verification of cryptographic algorithm strength is required to prevent potential decryption of sensitive information
• Defenders must assess exposure to potential decryption of highly sensitive information in IBM Concert 1.0 through 3.0.0 deployments

Technical summary

IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms, which could allow an attacker to decrypt highly sensitive information. The CVSS score is 3.7, indicating a low severity. This vulnerability affects IBM Concert deployments, and defenders should prioritize verifying the use of weak cryptographic algorithms and assessing exposure to potential decryption. The CVE record and source item indicate that IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms, which could allow an attacker to decrypt highly sensitive
