The flaw existed in the WooCommerce Checkout Manager that could allow a potential attacker to execute arbitrary file uploads. What’s risky here is that the researchers have made full disclosure of the flaw due to conflicts in the WordPress forum with moderators.

“Due to the moderators of the WordPress Support Forum’s continued inappropriate behavior we are full disclosing vulnerabilities in protest until WordPress gets that situation cleaned up.”

The researchers from the Plugin Vulnerabilities have described the flaw along with the proof of concept in their blog post. As reported, a flaw existed in the ‘Categorized File Upload’ setting of the plugin. While the plugin has the file upload feature inactive by default, an enabled ‘Categorized File Upload’ option could allow an attacker to upload any .php file to a location they could access.
