On May 14, 2026, security researcher Orange Tsai demonstrated a Microsoft Edge sandbox escape at Pwn2Own Berlin, one of the world’s premier hacking competitions. He was the only contestant to win the browser category, earning $175,000. The organizers later revealed that his exploit chained together four logic bugs rather than relying on the memory-corruption vulnerabilities commonly used in browser exploitation. The news sparked intense discussion across the global security community, but the mechanics of the attack remained unknown.
