Discourse is an open source discussion platform. Prior to version 2.8.0.beta11 in the tests-passed
branch, version 2.8.0.beta11 in the beta
branch, and version 2.7.13 in the stable
branch, the bios of users who made their profiles private were still visible in the <meta>
tags on their users pages. The problem is patched in tests-passed
version 2.8.0.beta11, beta
version 2.8.0.beta11, and stable
version 2.7.13 of Discourse.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are incorrectly applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
