Description
The Stream plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the user filter on the Stream records screen in all versions up to, and including, 4.4.0 due to insufficient output escaping of user-controlled user labels (such as display names) rendered in the user filter dropdown. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that will execute whenever an administrator or other privileged user accesses the Stream records screen.
