## Technical details

A reflected Cross-Site Scripting (XSS) vulnerability exists in the Quiz And Survey Master plugin for WordPress due to improper neutralization of user-supplied input during web page generation (CWE-79). The flaw allows an unauthenticated remote attacker to execute arbitrary JavaScript in the context of a user's browser session. Exploitation requires a victim to interact with a malicious link or crafted page (User Interaction: Required).
