CVE-2025-32803

Local client-data disclosure via world-readable files

Published May 28, 2025 · Updated May 28, 2025

Incorrect file permissions in Internet Systems Consortium Kea DHCP allow local users to read DHCP client data from affected log or lease files. Affected file-handling paths leave those files world-readable, exposing MAC addresses, hostnames, IP addresses, configuration details, and Kea internals. A local unprivileged account is required; the affected lines are 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8.
