CVE-2025-10147 is a critical unrestricted file upload vulnerability in the Podlove Podcast Publisher plugin for WordPress affecting all versions up to and including 4.2.6. The flaw is caused by missing file type validation in the plugin's move_as_original_file function, which processes uploaded media associated with podcast content. Because the vulnerable code path does not properly restrict uploaded file types, an unauthenticated attacker can submit a crafted request containing an arbitrary file, including server-executable content. If the uploaded file is stored in a web-accessible location and interpreted by the server, the issue can be leveraged for remote code execution on the affected WordPress host.
