Monthly
Heap-based buffer overflow in Hitachi Energy MACH HiDraw's XML parser allows a low-privileged, locally authenticated attacker to corrupt heap memory by inducing a victim to open a specially crafted XML file, with a primary impact of high availability loss (application crash) and limited confidentiality and integrity compromise. Affected versions span MACH HiDraw 9.0 through versions prior to 9.22 per EUVD-2026-31812. No public exploit identified at time of analysis, and an EPSS score of 0.01% (3rd percentile) combined with an SSVC exploitation status of 'none' confirm minimal current real-world exploitation activity.
