The Zephyr Project Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘message’ parameter in all versions up to, and including, 3.3.205 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability can only be exploited when the 'Directly link to project' plugin setting is disabled.
