CVE-2026-102132: Kiteworks Core Privilege Escalation through Improper Access Control

• Severity: high (CVSS 7.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.0% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-09-30 · updated 2026-10-07
• Weakness: CWE-284

Description

An administrative import function in Kiteworks Core did not verify that the requesting administrator was entitled to create the privileged integration credential being imported. A delegated administrator holding a single narrowly scoped administrative permission could therefore obtain full system administrator privileges, without any action by an existing system administrator.

Affected products
