Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker < 11.2.8 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 11.2.7. This is 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.
