Orange Tsai Shows Logic‑Bug Chain Escapes Microsoft Edge, $175K Pwn2Own Win

Researcher Orange Tsai published a sub‑100‑line exploit that uses only logic errors to break Edge’s sandbox, a technique that won $175,000 at the May Pwn2Own Berlin contest. Microsoft patched the vulnerabilities the day after the contest, so current Edge versions are not vulnerable.

Edge’s logic‑error escape highlights the need to prioritize sandbox hardening in browser roadmaps; users will expect robust isolation.
