CVE-2025-52657Network attack vector

Service degradation via unrestricted input length

Published Sep 7, 2026 · Updated Sep 8, 2026

Denial of service in HCL Software MyXalytics 6.6, 6.7, 6.8, and 6.8.0.1 allows remote authenticated users to degrade service via oversized input. The input-handling path accepts an unrestricted number of characters, but HCL has not disclosed the affected field, endpoint, or resource consumed. Exploitation requires a low-privileged account and user interaction, and the documented consequence is reduced performance or availability rather than data access or modification.
