Cross-Site Scripting in keystone
Versions of `keystone` prior to 4.0.0 are vulnerable to Cross-Site Scripting (XSS). The package fails to properly encode rendered HTML on admin-created blog posts. This allows attackers to execute arbitrary JavaScript in the victim's browser. Exploiting this vulnerability requires having access to an admin account. ## Recommendation Update to version 4.0.0 or later.
