Discourse vulnerable to Cross-site Scripting through pending post titles descriptions
Summary
Discourse vulnerable to Cross-site Scripting through pending post titles descriptions
Original description
The description as published by the source.
Discourse is an option source discussion platform. Prior to version 2.8.14 on the stable branch and version 3.0.0.beta16 on the beta and tests-passed branches, pending post titles can be used for cross-site scripting attacks. Pending posts can be created by unprivileged users when a category has the "require moderator approval of all new topics" setting set. This vulnerability can lead to a full XSS on sites which have modified or disabled Discourse’s default Content Security Policy. A patch is available in versions 2.8.14 and 3.0.0.beta16.
