Think of it like a poorly designed theme park attraction where a sneaky guest slips through the safety barriers and accesses restricted areas without a ticket.

If exploited, an attacker could manipulate the user’s browsing session, potentially leading to unauthorized access to sensitive data or malicious actions performed on the user's behalf. While there’s no known exploitation, the possibility is alarming enough to warrant attention!
