CVE-2026-111627 · HestiaCP before 1.10.5 Protected Admin Bypass via Cron Job Creation
This page contains facts from public vulnerability sources. Check the original advisory before updating.
HestiaCP before 1.10.5 contains an authorization bypass vulnerability that allows non-ROOT_USER administrators to perform write actions while impersonating the protected ROOT_USER account. Attackers can log in via the loginas parameter and POST to /add/cron/, because the read-only flag is never checked, causing crond to run their commands as the protected administrator's system account.
