What is CVE-2025-32802?

The Kea DHCP server has a vulnerability that allows misconfigured API directives to lead to arbitrary file overwrites. This can occur when Kea is operated with elevated permissions, such as running as a root user, and when its API entry points are left unsecured. Additionally, insecure control socket paths can expose the server to risks, permitting unauthorized file modifications. Affected versions include Kea 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.

Affected Version(s)

Kea 2.4.0 <= 2.4.1

Kea 2.6.0 <= 2.6.2

Kea 2.7.0 <= 2.7.8
