CVE-2026-102129: Accellion Kiteworks

High severity, CVSS 7.2. EPSS: 0.8% chance of exploitation in the next 30 days.

A user-provisioning interface in Kiteworks Core did not verify that the requesting administrator was entitled to grant the role being assigned. An administrator whose delegated permissions covered role changes alone could therefore raise an account to full system-administrator privileges.

Affected products

• Accellion Kiteworks: before 9.5.1 (fixed in 9.5.1)
