CVE-2026-109324Grav before 2.1.7 Memory Exhaustion via Oversized Image Transforms

Beschreibung

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.
