Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the GetPreview and resizeImage functions during image preview generation. An attacker can exhaust CPU and memory resources by uploading highly compressed images with extremely large dimensions, which are then fully decoded and resized without bounds. This can degrade or crash the service when multiple attachments or concurrent requests are processed. This is only exploitable if task attachments are enabled and the attacker is an authenticated user with write access to a task.
