| Package | Affected versions | Patched versions |
|---|---|---|
| keystone | = 4.0.0≤ 0.3.22 | |
| keystone | < 4.0.0-beta7 | 4.0.0-beta7 |
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.
Update to version 4.0.0 or later.
