CVE-2023-44216 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.. EPSS estimates a 1.81% chance of exploitation in the next 30 days.
