 "title": "پارسی دیت – Parsi Date <= 6.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Calendar Block 'theme' Attribute",
 "description": "The Parsi Date plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Calendar block's 'theme' attribute in all versions up to, and including, 6.4 due to insufficient input sanitization and output escaping. The theme value is placed directly into the class attribute of the calendar table. 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 a page containing the calendar block.",
