The Uncode theme for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.12.7. This is due to insufficient input sanitization and output escaping.
This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 2.12.8, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
