Elfsight Telegram Chat CC <= 1.1.0 - Missing Authorization to Authenticated (Subscriber+) Stored Cross-Site Scripting

The Elfsight Telegram Chat CC plugin for WordPress is vulnerable to unauthorized modification of data to a missing capability check on the 'updatePreferences' function in all versions up to, and including, 1.1.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
