What the vulnerability does
The Quiz and Survey Master plugin for WordPress is vulnerable to iFrame Injection via the 'question[id]' parameter in versions up to, and including, 8.0.4 due to insufficient input sanitization and output escaping that allowed iframe tags to be injected. This makes it possible for unauthenticated attackers to inject iFrames in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Quiz and Survey Master versions up to 8.0.4 contain an input validation flaw that allows unauthenticated attackers to read and modify limited data across the site. The vulnerability requires no user interaction and can be exploited over the network. Site administrators should update to a version newer than 8.0.4 immediately.
What an attacker can do
Read and modify some site data without logging in.
Potential impact on your site
Unauthorized users can access and alter quiz/survey data and potentially other site information.
