Technical details

The vulnerability is an authorization bypass in the /add/cron/ endpoint that fails to enforce the read-only flag when a non-ROOT_USER administrator attempts to add cron jobs while impersonated as ROOT_USER via the loginas parameter. The v-add-cron-job command executes with the impersonated user's privileges (root), and input validation uses quoteshellarg but lacks authorization checks, allowing arbitrary scheduled command execution.
