Description
The VK All in One Expansion Unit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vkExUnit_cta_url' and 'vkExUnit_cta_button_text' parameters in all versions up to, and including, 9.112.1. This is due to a logic error in the CTA save function that reads sanitization callbacks from the wrong variable ($custom_field_name instead of $custom_field_options), causing the sanitization to never be applied. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that execute when a user accesses an injected page.",

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the VK All in One Expansion Unit plugin for WordPress. It occurs because the plugin's CTA save function uses the wrong variable to apply sanitization callbacks, resulting in no sanitization being applied. Authenticated users with Contributor-level access or higher can inject malicious scripts into pages, which then execute when other users access those pages.

Impact Analysis

An attacker with Contributor-level access or higher can exploit this vulnerability to inject arbitrary scripts into web pages. This can lead to unauthorized actions such as stealing user credentials, session hijacking, defacing websites, or spreading malware to users who visit the affected pages.
