Summary

The Wavr plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the `wave` shortcode. This is due to insufficient input sanitization and output escaping on user supplied attributes.

Risk Assessment

Authenticated attackers with contributor-level access or higher can inject arbitrary scripts that execute whenever a user accesses an injected page, potentially leading to session theft or other attacks.

Recommendation

Update the Wavr plugin to version 0.2.7 or later.

Original NVD description (English source)

The Wavr plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `wave` shortcode in all versions up to, and including, 0.2.6. This is 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.
