This makes it possible for unauthenticated attackers to write arbitrary permission keys into the plugin's settings, causing `wps_ic_users::checkAndAddCaps()` to grant any WordPress role \u2014 including Subscriber \u2014 the `manage_wpc_settings` capability and thereby achieve plugin-administrator-equivalent control over the plugin's optimization, CDN, and critical-CSS surfaces. The API key required to pass the authorization check can itself be obtained without authentication via the `wpc_send_critical_remote` nopriv AJAX action: when the external critical-CSS service returns an `apiResults` field, `initCritical()` echoes the stored plugin API key back to the caller in a `wp_send_json_success` response, completing the exploit chain entirely without a WordPress login.\nhttps://www.cve.org/CVERecord?id=CVE-2026-104755https://www.wordfence.com/threat-intel/vulnerabilities/id/67e9bfb8-b274-422a-a50d-a6b6b24bb193?source=cvehttps://plugins.trac.wordpress.org/browser/wp-compress-image-optimizer/tags/7.10.03/classes/comms.class.php#L49https://plugins.trac.wordpress.org/browser/wp-compress-image-optimizer/tags/7.10.03/classes/users.class.php#L30https://plugins.trac.wordpress.org/browser/wp-compress-image-optimizer/tags/7.10.03/classes/comms.class.php#L1042https://plugins.trac.wordpress.org/browser/wp-compress-image-optimizer/tags/7.10.03/classes/ajax.class.php#L816https://plugins.trac.wordpress.org/browser/wp-compress-image-optimizer/tags/7.10.03/addons/criticalCss/criticalCss.php#L409https://plugins.trac.wordpress.org/changeset?reponame=&new=3734610%40wp-compress-image-optimizer%2Ftags%2F7.26.00&old=3723132%40wp-compress-image-optimizer%2Ftags%2F7.25.00#wordpress
