CVE-2024-43178Network attack vector

Sensitive-information decryption via weak cryptographic algorithms

Published Feb 17, 2026 · Updated Feb 17, 2026

Weak cryptography in IBM Concert 1.0.0 through 2.1.0 allows remote attackers to decrypt highly sensitive information over the network. IBM has not published the affected component, algorithm, or operation that exposes protected data to decryption. Exploitation requires unspecified high-complexity conditions without authentication or user interaction; no integrity or availability impact is reported.
