CVE-2026-93005 · Severity: medium · CVSS 6.5 · Published 2026-11-08

IBM Process Mining is a business process analytics tool used to monitor and optimize enterprise workflows. An authenticated user can exploit insufficient rate limiting on email notifications to flood targeted recipients with excessive emails, disrupting communication and creating a denial of service condition. This requires an attacker with valid credentials to the system.

## Technical details

An authenticated attacker can bypass email notification rate limiting in IBM Process Mining to trigger excessive email sends to arbitrary recipients, causing denial of service through resource exhaustion. The vulnerability resides in the email notification system's lack of throttling controls. An attacker with valid authentication can repeatedly trigger notification events without limits, resulting in spam-level email delivery.
