In short

Discourse exposes banner topic data to unauthenticated users on sites that require login. An attacker can access sensitive banner information without having an account or logging in.

Technical detail

An information disclosure vulnerability in Discourse versions prior to 2.8.4 (stable) and 2.9.0.beta5 (beta/tests-passed) allows unauthenticated attackers to retrieve banner topic metadata through improper access controls. The vulnerability requires the target site to have login requirements enabled; exploitation results in exposure of banner content that should be restricted to authenticated users.
