Podlove Podcast Publisher <= 4.5.1 - Arbitrary File Upload
CVE-2026-13001
Verified
Description
Podlove Podcast Publisher plugin for WordPress through 4.5.1 is vulnerable to arbitrary file uploads due to missing file type validation in the podlove_handle_cache_files function. The image cache derives the stored file extension from the path of the attacker supplied source URL, while the image validation is performed against a different file name taken from the full source URL, so a source URL whose path carries a dangerous extension is written to the cache with that extension.
