Multi Functional Flexi Lightbox
Monthly
A Stored Cross-Site Scripting vulnerability exists in the Multi Functional Flexi Lightbox WordPress plugin (versions up to and including 1.2) that allows authenticated administrators to inject arbitrary JavaScript code via the arv_lb[message] parameter. The vulnerability stems from insufficient input sanitization in the arv_lb_options_val() callback function and missing output escaping in the genLB() function, enabling malicious scripts to execute in the browsers of any user viewing pages or posts with the lightbox enabled. With a CVSS score of 5.5 and requiring high-privilege administrator access, this represents a moderate but real risk primarily applicable to compromised or malicious admin accounts.
