CVE-2026-1821 - Microtango Plugin
The Microtango plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'restkey' parameter of the mt_reservation shortcode in all versions up to, and including, 0.9.29 due to insufficient input sanitization and output escaping. 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.
