Football Pool < 2.11.10 - Authenticated (Subscriber+) Stored Cross-Site Scripting

Description

The Football Pool plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'answer' parameter in versions up to, and including, 2.11.9 due to insufficient input sanitization and output escaping. 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.
