Discourse is an open source discussion platform. When editing a topic, there is a vulnerability that enables a user to bypass the topic title validations for things like title length, number of emojis in title and blank topic titles. The issue is patched in the latest stable, beta and tests-passed version of Discourse.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
