Vulnerability from cvelistv5 – Published: 2021-07-27 21:40 – Updated: 2024-08-03 23:33

Title

Post creator of a whisper post can be revealed to non-staff users in Discourse

Summary

Discourse is an open source discussion platform. In versions prior to 2.7.7 there are two bugs which led to the post creator of a whisper post being revealed to non-staff users. 1: Staff users that creates a whisper post in a personal message is revealed to non-staff participants of the personal message even though the whisper post cannot be seen by them. 2: When a whisper post is before the last post in a post stream, deleting the last post will result in the creator of the whisper post to be revealed to non-staff users as the last poster of the topic.
