A vulnerability has been discovered in the Elementor Pro Plugin that could allow for remote code execution. This vulnerability can be exploited if user registration is enabled on the affected site. If enabled, registered users can upload arbitrary files which can lead to remote code execution.
Wordfence notes there is a workaround to bypass the registration requirement to exploit the vulnerability. If Ultimate Addons for Elementor is also used on the same Wordpress site, threat actors can exploit a separate vulnerability affecting Ultimate Addons to register as a subscriber-level user. Subscriber-level users would then be able exploit the vulnerability in Elementor Pro, that could allow for remote code execution.
