CVE-2026-7523 alejo30 CVE debrief

The Alba Board plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to access arbitrary private alba_card post data, including title, description, assignee, due date, tags, and comments, that is intended to be restricted to Administrators and Editors. The handler is registered via the wp_ajax_nopriv_ hook and its nonce is exposed to all site visitors through wp_localize_script on pages containing the [alba_board] shortcode, making this exploitable by unauthenticated users who can access any such page.
