CVE-2026-3347
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory (reason: Security Issue), and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
The Multi Functional Flexi Lightbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the arv_lb[message] parameter in all versions up to, and including, 1.2 due to insufficient input sanitization and output escaping. This is due to the arv_lb_options_val() sanitize callback returning user input without any sanitization, and the stored message value being output in the genLB() function without escaping. This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses a page or post with the lightbox enabled.
