CVE-2026-8911 Details
Description
The WP AutoBuzz plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.1. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This vulnerability bypasses WordPress's DISALLOW_UNFILTERED_HTML protection because the unsanitized value is written directly via update_option at the plugin level, entirely outside of WordPress post content handling.
A Cross-Site Request Forgery (CSRF) vulnerability exists in the WP AutoBuzz plugin for WordPress, affecting all versions through 1.1.1. The issue arises from inadequate nonce validation, allowing unauthenticated attackers to manipulate settings and inject harmful web scripts by tricking a site administrator into clicking a link. This vulnerability circumvents WordPress's DISALLOW_UNFILTERED_HTML safeguard, as the unfiltered data is directly saved via the update_option function at the plugin level, bypassing WordPress's standard content management.
No known patch is available. It is recommended to review the vulnerability details and consider uninstalling the affected plugin.
