Technical details
A pre-authenticated attacker can inject HTML into a failed-login email value, which is copied into a SendAlert job. If alert delivery fails, the serialized payload is stored in the failed_jobs table. The /system/ajax-html/job_details/{id} endpoint renders this content with insufficient sanitization (blacklist-based), leaving executable event-handler attributes intact. When viewed as a top-level page, the lack of normal layout Content Security Policy allows attacker-controlled JavaScript execution in administrator context.
