CVE-2026-33765 describes a critical OS Command Injection vulnerability (CWE-78) in the Pi-hole Admin Interface, affecting versions prior to 6.0. This flaw allows an attacker to inject arbitrary system commands via the 'webtheme' parameter in savesettings.php, which is directly executed without proper sanitization. Rated with a CVSS score of 8.9 (HIGH), it is remotely exploitable over the network with low attack complexity, requiring no authentication or user interaction, and grants an attacker the ability to execute arbitrary commands with elevated (likely root) privileges. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, and its EPSS score is very low, indicating a low probability of exploitation in the wild.
