FTLDNS (pihole-FTL) provides an interactive API and also generates statistics for Pi-hole's Web interface.

Published Apr 7, 2026 · updated Jun 17, 2026 · pi-hole ftldns

FTLDNS (pihole-FTL) provides an interactive API and also generates statistics for Pi-hole's Web interface. From 6.0 to before 6.6, the Pi-hole FTL engine contains a Remote Code Execution (RCE) vulnerability in the DNS CNAME records configuration parameter (dns.cnameRecords). This vulnerability allows an authenticated attacker to inject arbitrary dnsmasq configuration directives through newline characters, ultimately achieving command execution on the underlying system. This vulnerability is fixed in 6.6.
