What the vulnerability does
The ACF Onyx Poll plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘class’ parameter in all versions up to, and including, 1.1.9 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.
Explanation of Vulnerability in Simple Terms
ACF Onyx Poll versions up to 1.1.9 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability affects the poll functionality and can impact other users viewing the site. The scope is changed, meaning the attack can extend beyond the vulnerable component itself.
What an attacker can do
Inject malicious scripts that execute in other users' browsers when they view poll content.
Potential impact on your site
Authenticated users can inject scripts affecting other site visitors, potentially stealing session data or redirecting users.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required.
