Elementor, a WordPress website builder plugin with over five million active installations, has been found to be vulnerable to an authenticated remote code execution flaw that could be abused to take over affected websites. Plugin Vulnerabilities, which  disclosed  the flaw last week, said the bug was introduced in version 3.6.0 that was released on March 22, 2022. Roughly  37% of users  of the plugin are on version 3.6.x. "That means that malicious code provided by the attacker can be run by the website," the researchers said. "In this instance, it is possible that the vulnerability might be exploitable by someone not logged in to WordPress, but it can easily be exploited by anyone logged in to WordPress who has access to the WordPress admin dashboard." In a nutshell, the issue relates to a case of arbitrary file upload to affected websites, potentially leading to code execution. The bug has been addressed in the latest version of Elementor, with Patchstack

A WordPress plugin with over one million installs has been found to contain a critical vulnerability that could result in the execution of arbitrary code on compromised websites. The plugin in question is  Essential Addons for Elementor , which provides WordPress site owners with a library of over 80 elements and extensions to help design and customize pages and posts. "This vulnerability allows any user, regardless of their authentication or authorization status, to perform a local file inclusion attack," Patchstack  said  in a report. "This attack can be used to include local files on the filesystem of the website, such as /etc/passwd. This can also be used to perform RCE by including a file with malicious PHP code that normally cannot be executed." That said, the vulnerability only exists if widgets like dynamic gallery and product gallery are used, which utilize the vulnerable function, resulting in local file inclusion – an attack technique in which a web

Flaws in Two Popular WordPress Plugins Affect Over 7 Million Websites

Researchers have disclosed vulnerabilities in multiple WordPress plugins that, if successfully exploited, could allow an attacker to run arbitrary code and take over a website in certain scenarios. The flaws were uncovered in  Elementor , a website builder plugin used on more than seven million sites, and  WP Super Cache , a tool used to serve cached pages of a WordPress site. According to Wordfence, which discovered the security weaknesses in Elementor, the bug concerns a set of  stored cross-site scripting  (XSS) vulnerabilities (CVSS score: 6.4), which occurs when a malicious script is injected directly into a vulnerable web application. In this case, due to a lack of validation of the HTML tags on the server-side, a bad actor can exploit the issues to add executable JavaScript to a post or page via a crafted request. "Since posts created by contributors are typically reviewed by editors or administrators before publishing, any JavaScript added to one of these posts would
