Cross-origin pixel theft via PVRIC compression
Published Sep 26, 2023 · Updated Sep 24, 2024
Information disclosure in Imagination Technologies PowerVR GPU 2018 and later allows remote attackers to read cross-origin page pixels via SVG filters. PVRIC compression causes feTurbulence and feBlend rendering differences that act as a side channel for inferring text from another origin when attacker-controlled content is loaded. Exploitation requires a victim browser to render the attacker-controlled resource; reported impact is confidentiality only, with no integrity or availability effect.
