WordPress Hybrid Composer 1.4.6 contains an unauthenticated settings change vulnerability that allows unauthenticated attackers to modify WordPress options by exploiting the hc_ajax_save_option action. Attackers can send POST requests to the admin-ajax.php endpoint with the action parameter set to hc_ajax_save_option to enable user registration and set the default role to administrator, enabling account takeover.
Security readout for executives and security teams
CVE-2019-25738 lets an unauthenticated internet user change sensitive WordPress settings in Hybrid Composer 1.4.6. The reported impact is severe: attackers can enable registration, make new users administrators, and take over the site. Exposure is likely limited to WordPress sites running framework-y Hybrid Composer version 1.4.6. Internet-facing WordPress admin-ajax.php endpoints increase risk, but the bundle does not prove all versions or related products are affected. Treat this as urgent for any exposed WordPress estate. A successful attack can create administrator access without credentials, enabling full site compromise, content changes, data theft, malware placement, or operational disruption. Mitigation focus: Inventory WordPress sites for Hybrid Composer 1.4.6.; Check vendor or project guidance for a patched release or official fix.; Disable the affected plugin where business operations allow..
