The Redirection for Contact Form 7 plugin for WordPress is vulnerable to PHP Object Injection via the delete_associated_files function. This vulnerability arises due to the deserialization of untrusted input. Unauthenticated attackers can exploit this vulnerability when a form with a file upload action is present on the site. The presence of the ‘Redirection For Contact Form 7 Extension – Create Post’ extension further makes the vulnerability exploitable. With a POP chain present via an additional plugin or theme, the attacker can take actions like deleting arbitrary files, retrieving sensitive data, or executing code.<\/p>\n
