How To Fix WordPress file manager plugin vulnerability and security issue

 If you are still using the file manager versions 6.0–6.8 on WordPress, you need to upgrade immediately, here’s why!

The world witnessed a series of WordPress sites being hacked, and if you are still unaware of the WordPress security issues that surfaced recently due to the WordPress file manager plugin, here’s is all you need to know.

  • The WordPress File Manager versions 6.0–6.8 are being targetted and are the reason behind the WordPress Websites Attacked worldwide. A record of around 1.7 million sites has undergone a WordPress security issue in a matter of a few days now.
  • The file manager vulnerability attacks occurred due to the WordPress file manager plugin extension elFinder, an open-source library file, which was wrongly named to .php from connector.minimal.php.dist. This renaming allowed unauthenticated users to gain access to the file manager.
  • Hackers, before going with a malicious attempt on a WordPress site, have been trying to introduce harmless, empty files, to begin with, and upon gaining access to the website after successfully overcoming the WordPress cybersecurity, have submitted malicious files.
  • Wordfence, the WordPress security firm, has come up with a list of files that have been uploaded repeatedly, including hardfork.php, hardfind.php, and x.php. The most frequently uploaded file being Feoidasf4e0_index.php.
  • The hackers have been blocking other hackers from gaining access once taking over the admin control, which enables them to edit, upload, delete the contents of the website as they see fit.

The Wordfence Threat Intelligence team, upon being notified of the zero-day vulnerability, came up with a release of a patched version of the WordPress file manager plugin with a way to protect against the file manager vulnerability attacks.

Our cybersecurity experts at Infomaze suggest that you immediately upgrade your WordPress file manager plugin if you are still using the file manager versions 6.0–6.8 to the latest patched plugin version 6.9.


The patched version prevents hackers from exploiting the vulnerability by completely deleting the lib/php/connector.minimal.php file from the plugin. The same can be done manually while still maintaining the functionality and WordPress cybersecurity.

If you are not using the WordPress file manager plugin actively, we recommend that you uninstall it and activate it on a need-to basis.
