visualcomposer visual_composer_website_builder Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Published Oct 8, 2026 · corrected/updated Oct 8, 2026 · visualcomposer visual_composer_website_builder · evidence confidence very high
The Visual Composer Website Builder plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 45.16.0 via the parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. Initial-access exploit intelligence.
