WordPress XSS

Description

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.

Analysis

Stored Cross-Site Scripting in Wavr WordPress plugin up to version 0.2.6 allows authenticated contributors and above to inject arbitrary JavaScript via insufficiently sanitized shortcode attributes, with malicious scripts executing for all users who view affected pages. CVSS 6.4 reflects moderate severity with network-accessible attack vector and cross-site impact; no public exploit code or active exploitation confirmed at time of analysis.
