CVE-2021-27784Network attack vector

Protected-data disclosure via reused container cryptographic material

Published Oct 31, 2022 · Updated May 2, 2025

Cryptographic key reuse in HCL Launch container images allows remote attackers to read protected data over the network. The published images embed non-unique HTTPS certificate material and a database encryption key, causing separate deployments to reuse the same secrets. Exploitation requires access to traffic or encrypted database material from a container deployment; standard installer packages are unaffected.
