Authentication bypass in Restaurant Brands International Assistant through 2025-09-06 allows remote attackers to access its diagnostic screen. The hosted platform places the diagnostic-screen authentication decision in attacker-controlled client-side logic instead of enforcing it on the server. No credentials or user interaction are required, but the public record does not identify the diagnostic functions or data exposed.
