Description

The Contact Form 7 plugin for WordPress is vulnerable to Arbitrary File Upload in versions 6.2 through 6.2.3. This is due to missing file type validation. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server, which may make remote code execution possible.
