Sandbox escape via Accessibility type confusion
Published May 6, 2026 · Updated May 6, 2026
Type confusion in Google Chrome Accessibility on Windows before 148.0.7778.96 allows remote attackers to escape the renderer sandbox. The Accessibility component accesses a resource as an incompatible type, but Google keeps the issue details restricted and has not disclosed the affected object or operation. Exploitation requires a crafted HTML page, user interaction, and an already compromised renderer process; the result is escape from Chrome's sandbox boundary.
