CVE-2026-21753: HCL Hive weak software supply chain governance

CVE-2026-21753 · Severity: medium · CVSS 4.2 · Published 2026-08-25

Vendors: HCL.

Executive brief

HCL Hive is an application platform that relies on third-party software components to function. A weakness in how these dependencies are managed and verified could allow vulnerable or malicious code to be introduced into the application, potentially compromising data integrity, system stability, or security.

Technical details

This vulnerability stems from inadequate software supply chain governance practices in HCL Hive, resulting in insufficient vetting and maintenance of third-party dependencies. The weakness allows vulnerable, unmaintained, or potentially malicious third-party libraries to be included in the application environment without proper controls. While no active exploitation in the wild has been reported, the vulnerability creates a vector for downstream attacks if malicious or vulnerable dependencies are incorporated. The risk is heightened by the transitive nature of dependency chains and the difficulty in tracking provenance of all included components.
