CVE-2023-36466: Topic Title Validation Skipped When Changing Category in Discourse
Published Jul 14, 2023
·Updated
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.
