Privilege Escalation via update_event Job Output in Cronicle

Description

Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.111, jb child processes can include an update_event key in their JSON output. The server applies this directly to the parent event's stored configuration without any authorization check. A low-privilege user who can create and run events can modify any event property, including webhook URLs and notification emails. This vulnerability is fixed in 0.9.111.
