Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the VK All in One Expansion Unit plugin for WordPress. It occurs via the '_veu_custom_css' parameter due to insufficient input sanitization and output escaping of user-supplied Custom CSS. Authenticated attackers with Contributor-level access or higher can inject arbitrary web scripts that execute when users access the affected pages.
How can this vulnerability impact me? :
The vulnerability allows attackers to inject malicious scripts into web pages, which can lead to unauthorized actions such as stealing user credentials, hijacking user sessions, defacing websites, or delivering malware to visitors. Since the attack requires Contributor-level access, it could be exploited by insiders or compromised accounts to affect other users.
