A critical Avada Builder WordPress plugin vulnerability tracked as CVE 2026 8713 allows unauthenticated attackers to delete arbitrary files including wp config php leading to full site takeover and remote code execution on over one million websites.

Have you ever imagined that your entire website could be destroyed by just one form submission? No password theft no login attempt just a simple contact form you placed on your site yourself? This is the story that is currently happening to millions of WordPress users whose websites are running on the Avada Builder plugin and who were unaware of this threat until now.

Avada Builder Arbitrary File Deletion Vulnerability Explained

This vulnerability is being tracked as CVE 2026 8713 and has been given a very high score of 9.1 by the CVSS scoring system which directly proves how dangerous this issue is. The real threat is hidden inside the maybe delete files function of the plugin, where the file path is not properly validated. Due to this any unauthenticated attacker i.e., anyone without logging in can delete files on the server.

The attack method is very simple but clever. In Avada form builder feature, when a form is set up with database storage an attacker submits a crafted entry that includes directory traversal characters. For example and the attacker sends a path within the form that bypasses the upload folder and directly reaches the wp config php. The plugin automated privacy cleanup system processes this path without any checks and permanently deletes the targeted file using WordPress native delete function.

The most dangerous thing is that the attacker needs neither a login nor any admin interaction for this entire process. This cleanup routine is triggered automatically by simply controlling form parameters. And when a critical file like wpconfig.php is deleted WordPress automatically returns to its setup screen where the attacker can connect their malicious database and take over the entire site ultimately leading to remote code execution.

Patch Update and Site Takeover Risk Mitigation

This issue was discovered by security researcher Daroo and reported through the Wordfence Bug Bounty Program on May 13, 2026. The researcher was rewarded with $3600 for his hard work. Wordfence validated this report and sent it to the vendor on May 15 and the Avada team fixed this issue in just four days i.e., on May 19. The official fix was released on June 2, 2026 with Avada version 3.15.4.

All websites running version 3.15.3 or older are vulnerable to this attack. Therefore this is most important that website owners update their Avada Builder plugin to the latest version immediately. Those using the Wordfence firewall already have protection because this firewall detects path traversal patterns within form data and blocks requests.

This incident is not just about one plugin. This is a really important truth that the thing which you consider to be the safest and most normal can sometimes destroy your entire digital world and hence the real security is to always look at every plugin and every update and every form with suspicion.
