CVE-2026-85742

Что произошло

FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.230, a pre-authenticated attacker can place HTML in a failed-login email value that is copied through monitored user activity into a queued SendAlert job. If alert delivery fails, the serialized payload is stored in failed_jobs and the administrator job-details endpoint renders it after a blacklist sanitizer that leaves executable event-handler attributes. When an administrator opens /system/ajax-html/job_details/{id} as a top-level page, the raw fragment lacks the normal layout policy and attacker-controlled JavaScript can perform same-origin administrator actions. Logs Monitoring for users, a failed alert email job, queue failure storage, and top-level administrator interaction are all required; the normal modal path is not affected in the tested configuration. This issue is fixed in version 1.8.230.
