What the vulnerability does
The MediaView plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘id' parameter in all versions up to, and including, 1.1.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
MediaView versions 1.1.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. The vulnerability requires user interaction—a victim must visit a crafted link or page. Successful exploitation can compromise user sessions and steal sensitive data. Update to a version newer than 1.1.2.
What an attacker can do
Inject malicious scripts that execute in other users' browsers when they visit a crafted page.
Potential impact on your site
User accounts and sessions at risk; attackers can steal credentials, session tokens, or perform actions on behalf of victims.
Conditions required to exploit
No authentication required. Victim must click a malicious link or visit an attacker-controlled page.
