Podlove Podcast Publisher <= 4.5.1 - Unauthenticated Arbitrary File Upload via podlove_image_cache_url Parameter

9.8 CriticalPublic exploit

The Podlove Podcast Publisher plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'podlove_handle_cache_files' function in all versions up to, and including, 4.5.1.
