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.
Affected configurations
