CVE-2026-21754: HCL Hive infrastructure and network configuration vulnerabilities

CVE-2026-21754 · Severity: medium · CVSS 5.4 · Published 2026-08-25

Vendors: HCL.

Executive brief

HCL Hive is a software platform affected by multiple infrastructure and network security misconfigurations. These vulnerabilities could allow attackers to move laterally across internal systems, break out of containers, and expose sensitive internal communications—potentially compromising the integrity and confidentiality of the entire platform and data it handles.

Technical details

HCL Hive is affected by multiple infrastructure and network configuration vulnerabilities that could enable unauthorized lateral movement, container escape, and sensitive data exposure. The vulnerabilities stem from improper configuration of network isolation and container security boundaries. An attacker with initial access to the system or network could exploit these misconfigurations to move laterally to other systems and sensitive data. Container breakout conditions may allow privilege escalation and access to the underlying host. Patches or configuration hardening guidance should be obtained from HCL's support documentation.
