Name of the Vulnerable Software and Affected Versions Discourse versions prior to the latest stable, beta and tests-passed version

Description The issue is related to insufficient input validation when processing topic titles, allowing a remote attacker to impact the integrity and availability of protected information. The vulnerability enables a user to bypass topic title validations, such as title length, number of emojis in the title, and blank topic titles, when editing a topic.

Recommendations For versions prior to the latest stable, beta and tests-passed version, update to the latest stable, beta or tests-passed version to resolve the issue. As a temporary workaround, consider restricting the ability to edit topic titles until the update is applied.
