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, the number of times a user posted in an arbitrary topic is exposed to unauthorized users through the /u/username.json
endpoint. The issue is patched in version 2.8.14 and 3.0.0.beta16. There is no known workaround.
