Cross-origin data disclosure after renderer compromise
Published Sep 1, 2026 · Updated Sep 2, 2026
Information exposure in Skia in Google Chrome before 152.0.7977.75 allows remote attackers to leak cross-origin data via crafted HTML. Google has not disclosed the faulty Skia operation or how crafted page content crosses the origin boundary. Exploitation requires prior compromise of Chrome's renderer process, and the documented consequence is disclosure of cross-origin data.
