| Package | Affected versions | Patched versions |
|---|---|---|
| wpml | ≥ 3.6.0, < 4.7.4 | 4.7.4 |
The WPML plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpml_language_switcher shortcode in versions 3.6.0 - 4.7.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
