What the vulnerability does
The Wonder Slider Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image title and description DOM in all versions up to, and including, 14.4 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
Wonder Slider versions 14.4 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has changed scope, meaning injected code can affect other users or site functionality beyond the plugin itself. An attacker with low-level site access can exploit this without user interaction.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers or affects site functionality.
Potential impact on your site
Other site users may have their sessions hijacked, credentials stolen, or be redirected to malicious sites.
Conditions required to exploit
Attacker must have low-level authenticated access to the site (e.g., subscriber or contributor role).
