## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
