A remote code execution vulnerability has been identified in the OrdaSoft Joomla Gallery extension for Joomla versions prior to 6.2.7. The issue arises in the extension's updateOSGallery() method, which is accessed via task=update_osgallery. This method reads a JSON request body and executes the value of a method field as a live PHP function, passing the value of a package field as its sole argument. Notably, there are no allow-list checks or validations to ensure the function name is callable. As a result, any function compatible with a single argument, including system, exec, shell_exec, and passthru, can be invoked directly.
