Description

The contact-form-7 (aka Contact Form 7) plugin before 5.3.2 for WordPress allows Unrestricted File Upload and remote code execution because a filename may contain special characters.

MergeBase Comment

An unrestricted file upload vulnerability has been found in Contact Form 7 5.3.1 and older versions. Utilizing this vulnerability, a form submitter can bypass Contact Form 7’s filename sanitization, and upload a file which can be executed as a script file on the host server.

If you have Contact Form installed and allow any file uploads on any form, it is important to upgrade the plugin immediately. Due to the ubiquity of WordPress sites, you may be hit by drive-by automated attacks in addition to targeted attacks.
