Carga sin restricciones de archivos con vulnerabilidad de tipo peligroso en Jeff Starr User Submitted Posts – Enable Users to Submit Posts from the Front End. Este problema afecta a User Submitted Posts – Enable Users to Submit Posts from the Front End desde n/a hasta 20230902.

The User Submitted Posts plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the usp_attach_images function in versions up to, and including, 20230902. This makes it possible for unauthenticatedattackers to upload arbitrary files as long as the extension does not contain 'php' on the affected site's server which may make remote code execution possible.
