Discourse is an open source discussion platform. In versions prior to 2.8.9 on the stable branch and prior to 2.9.0.beta10 on the beta and tests-passed branches, a malicious actor can add large payloads of text into the Location and Website fields of a user profile, which causes issues for other users when loading that profile. A fix to limit the length of user input for these fields is included in version 2.8.9 on the stable branch and version 2.9.0.beta10 on the beta and tests-passed branches. There are no known workarounds.
