CVE-2026-111627 Details
Description
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.
An authorization bypass vulnerability has been identified in HestiaCP versions prior to 1.10.5. This vulnerability allows non-ROOT_USER administrators to impersonate the ROOT_USER account and perform write actions, such as adding cron jobs. The issue arises because the read-only flag is not properly enforced, allowing injected commands to be executed under the protected administrator's system account via cron.
Users can update to HestiaCP version 1.10.5 or later, where this vulnerability has been patched.
