Grav 1.7.53 before 1.7.53.5 and 2.0.0-rc.8 before 2.2.2 contains a resource exhaustion vulnerability that allows anonymous visitors to bypass the system.images.max_pixels limit when system.images.url_actions is enabled. Attackers can send single-dimension or percentage forceResize, zoomCrop, or chained image actions to make GD allocate multi-gigabyte canvases, exhausting server memory and taking the site down.
