CVE-2026-50130Public exploit

Root escalation via logrotate ownership laundering

Published Jul 14, 2026 · Updated Jul 14, 2026

Improper ownership management in Pi-hole 6.0 through 6.4.2 allows local users running as pihole to execute shell commands as root. The root-context pihole-FTL-prestart.sh hook changes a replacement /etc/pihole/logrotate file to root ownership without validating its contents. Code execution as the pihole user permits replacement and a service restart; the daily root cron then parses firstaction as uid 0.
