The Wordfence Threat Intelligence Team recently identified an interesting malware family on May 16, 2025 during a site clean. This malware family shared a codebase but varied in features across different versions, including credit card skimming and WordPress credential theft. Most surprisingly, one variant incorporated a live backend system hosted directly on infected websites for attacker use – a previously unseen method – packaged and disguised as a rogue WordPress plugin.

On May 2nd, 2025, we received a submission for a Privilege Escalation vulnerability in Motors, a WordPress theme with more than 22,000 sales. This vulnerability makes it possible for an unauthenticated attacker to change the password of any user, including an administrator, which allows them to take over the account and the website. We originally disclosed this vulnerability on May 19th, 2025 and our records indicate that attackers started exploiting the issue the next day on May 20th, 2025. It appears mass exploitation started on June 7th, 2025. The Wordfence Firewall has already blocked over 23,100 exploit attempts targeting this vulnerability.

On May 21st, 2025, our Wordfence Threat Intelligence team identified and began the responsible disclosure process for an Insufficient Authorization to Privilege Escalation via MCP (Model Context Protocol) vulnerability in the AI Engine plugin, which is actively installed on more than 100,000 WordPress websites. This vulnerability can be exploited by authenticated attackers, with subscriber-level access and above, to get full access to the MCP and execute various commands like ‘wp_update_user’, allowing them to escalate their privileges to administrators by updating their user role. Please note that this vulnerability only critically affects users who have enabled the Dev Tools and then the MCP module in the settings, which is disabled by default.

On March 24th, 2025, we received a submission for an Arbitrary File Upload and an Arbitrary File Deletion vulnerability in WP User Frontend Pro, a WordPress plugin with an estimated 9,000 active installations. The arbitrary file upload vulnerability can be used by authenticated attackers, with subscriber-level access and above, to upload arbitrary files to a vulnerable site and achieve remote code execution, which is typically leveraged for a complete site takeover. The arbitrary file deletion vulnerability can be used by authenticated attackers to delete arbitrary files, including the wp-config.php file, which can also make a site takeover possible.

The Wordfence Threat Intelligence team recently discovered an interesting malware variant that appears in the file system as a normal WordPress plugin containing a comment header, a handful of functions as well as a simple admin interface. Just like previous examples we have seen, this piece of malware contains code that ensures it remains hidden in the administrator dashboard. It has a password extraction feature, which requires configuration through its own admin interface, an AJAX-based remote code execution mechanism and unfinished code suggesting it is still in development.

On May 15th, 2025, we received a submission for an Arbitrary File Upload vulnerability in MasterStudy LMS Pro, a WordPress plugin with more than 15,000 estimated active installations. The MasterStudy Education WordPress theme from ThemeForest with more than 21,000 sales also includes the Pro plugin. This vulnerability makes it possible for authenticated users such as subscribers to upload arbitrary files to a vulnerable site and achieve remote code execution in certain configurations, which is typically leveraged for a complete site takeover. Please note that this vulnerability only critically affects users who have enabled the “Media File Manager” and “Assignments” addons in the Pro plugin, both of which are disabled by default.

The Wordfence Threat Intelligence team recently uncovered a sophisticated formjacking malware targeting WooCommerce sites. This malware injects a fake payment form into legitimate checkout processes and exfiltrates sensitive customer data to a remote Command & Control (C2) server. Unlike traditional card skimmers that simply overlay existing forms, this variant carefully integrates with the WooCommerce site’s design and payment workflow, making it particularly difficult for site owners and users to detect.

On March 29th, 2025, we received a submission for a Remote Code Execution vulnerability in UiPress lite, a WordPress plugin with over 10,000 active installations. This vulnerability can be leveraged to execute code remotely, which makes it possible for attackers to do nearly anything like injecting backdoors, exfiltrating sensitive information, and injection malicious spam or SEO redirects just to name a few impacts.

On April 26th, 2024, we received a submission for an authenticated PHP Object Injection vulnerability in Uncanny Automator, a WordPress plugin with more than 50,000 active installations. This vulnerability can be leveraged via an existing POP chain present in the plugin to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution by authenticated subscriber-level attackers possible.

On May 4th, 2025, we received a submission for an Arbitrary File Upload vulnerability in TheGem, a WordPress theme with more than 82,000 sales. This vulnerability can be used by authenticated attackers, with subscriber-level access and above, to upload arbitrary files to a vulnerable site and achieve remote code execution, which is typically leveraged for a complete site takeover.
