MeWare PDKS Flooding Vulnerability: CVE-2026-7402 Impacts Time & Attendance Systems

The National Vulnerability Database has detailed CVE-2026-7402, a high-severity Improper Control of Interaction Frequency vulnerability affecting MeWare Software Development Inc.’s PDKS (Personnel Data Collection System) software. This flaw, rated 8.1 CVSS (High), specifically impacts PDKS versions from V16.20200313 before VMYR_3.5.2025117. An attacker can exploit this vulnerability to initiate a flooding attack.

This isn’t just a denial-of-service; it’s a systemic disruption.
