CVE-2025-62300Network attack vector

Resource modification via race condition

Published Aug 20, 2026 · Updated Aug 20, 2026

Race condition in HCL IntelliOps Event Management 1.4.0 allows remote attackers to modify resources via concurrent requests. HCL has disclosed only that a timing window lets unsynchronized operations act on a shared resource after attacker-driven modification; no affected component, endpoint, or code path is public. The published CVSS vector sets PR:N and UI:N, so no authentication or user interaction is required, and the disclosed impact is limited to integrity changes and resulting unpredictable behavior rather than data disclosure or service interruption.
