Ninja Forms Scheduled Exports stores subscriber scripts through REST parameters
Ninja Forms - Scheduled Exports through 3.0.3 registers a REST endpoint without permission_callback and checks a nonce without checking user capabilities. A Subscriber or higher-privileged user can submit script-bearing interval, format, or emailTo values. Insufficient sanitization and output escaping allow the stored input to execute as script when another user views affected content.

Technical description
The Ninja Forms - Scheduled Exports plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REST API Parameters (interval, format, emailTo) in all versions up to, and including, 3.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level privileges and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The REST endpoint is registered without a permission_callback and only validates a nonce without checking user capabilities.
