NewCVE-2026-112782 (opens in a new tab)How to fix?
Upgrade getgrav/grav to version 1.7.53.5, 2.2.2 or higher.
Overview
getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via Grav::fallbackUrl() when processing image URL actions, due to an incomplete pixel-ceiling check. The system.images.max_pixels limit only compared the width and height values literally present in the query string, and only when both were explicitly provided. An attacker can bypass the limit by supplying a single dimension (e.g. forceResize=46000 on a square source allocates a 46000x46000 canvas) or by using zoomCrop with a minimal second argument, causing GD/Imagick to allocate a canvas of widthheight4 bytes outside PHP's memory_limit and exhausting server RAM.
Note: This is only exploitable when system.images.url_actions is enabled.
