CVE-2025-32801 (opens in a new tab)How to fix?
Upgrade isc-projects/kea to version 2.4.2, 2.6.3, 2.7.9 or higher.
Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the configuration and API directives. An attacker can escalate privileges by loading a malicious hook library. This is only exploitable if Kea is run as root, the API entry points are unsecured, and the control sockets are placed in insecure paths.
Workaround
This vulnerability can be mitigated by either disabling the Kea API entirely, by disabling the kea-ctrl-agent, and removing any "control-socket" stanzas from the Kea configuration files; or securing access to the API by requiring authentication for the kea-ctrl-agent, and configuring all "control-socket" stanzas to use a directory restricted to only trusted users.
