CVE-2026-102113: Accellion Kiteworks

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

A privilege escalation vulnerability in Kiteworks could allow an attacker who has already obtained code execution as an unprivileged backend service account on the appliance to escalate to root. A privileged routine did not safely handle a filesystem path that the lower-privileged account could influence, allowing the attacker to cause a root-owned operation to run arbitrary commands with the highest privileges. Exploitation requires existing local access to that service account.

Affected products

• Accellion Kiteworks: before 9.5.0 (fixed in 9.5.0)
