What the vulnerability does
01Description
The WP Airbnb Review Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.2 due to insufficient URL validation that allows users to pull in a malicious HTML file. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Explanation of Vulnerability in Simple Terms
02Summary
WP Airbnb Review Slider versions 4.2 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated admin with high privileges can inject malicious scripts into the plugin settings. When other users view affected pages, the injected code executes in their browsers, potentially stealing session data or performing actions on their behalf. The vulnerability requires admin access and user interaction to trigger.
