What the vulnerability does

01Description

The Blubrry PowerPress plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in all versions up to, and including, 11.15.2. This is due to the plugin validating file extensions but not halting execution when validation fails in the 'powerpress_edit_post' function. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Explanation of Vulnerability in Simple Terms

02Summary

The PowerPress Podcasting plugin for WordPress contains an unrestricted file upload vulnerability affecting versions up to 11.15.2. An authenticated user with low privileges can upload arbitrary files to the server without proper validation. This allows attackers to upload malicious code, potentially gaining control of the site. Update to a version newer than 11.15.2 immediately.
