HTML Injection in shout
Affected versions of `shout` do not escape the `/topic` command in messages, and are therefore vulnerable to cross-site scripting.
## Recommendation
Update to version 0.50.0 or later.

Because the `/topic` command in messages is unescaped, attackers have the ability to inject HTML scripts that will run in the victim's browser.
