Summary

Grav before 2.1.7 contains a denial of service vulnerability that allows authenticated media authors to exhaust memory by uploading compressed oversized raster images. Attackers can reference a Twig or Markdown transform so GD or Imagick decodes the full source without dimension checks, letting anonymous requests repeatedly cause page unavailability.

Risk Assessment

The risk includes server overload and page unavailability for all users, potentially leading to service disruptions and financial losses.

Recommendation

Update Grav to version 2.1.7 or later, which includes a fix to limit image processing.
