Unauthenticated Broken Authentication in SMS Alert Order Notifications <= 3.9.3 versions.

AnalysisAI

Authentication bypass in the WordPress plugin SMS Alert Order Notifications (versions <= 3.9.3) allows remote unauthenticated attackers to access functionality or data that should be restricted to authenticated users. The flaw, reported by Patchstack and tracked under CWE-862 (Missing Authorization), carries a CVSS 7.5 with high confidentiality impact only. There is no public exploit identified at time of analysis and the issue is not currently listed in CISA KEV.

Technical ContextAI

The affected component is SMS Alert Order Notifications, a WordPress plugin by Cozy Vision Technologies Pvt. Ltd. used by WooCommerce/WordPress site operators to send SMS notifications for order events. The CPE cpe:2.3:a:cozy_vision_technologies_pvt._ltd.:sms_alert_order_notifications confirms the vendor and product. CWE-862 (Missing Authorization) indicates that one or more plugin endpoints - typically AJAX actions or REST routes registered by the plugin - fail to enforce a capability check or nonce validation before performing a privileged operation or returning sensitive data, allowing requests from unauthenticated sources to be processed as if authorized.

RemediationAI

Upstream fix available per Patchstack advisory; released patched version not independently confirmed from the provided data, so administrators should upgrade SMS Alert Order Notifications to the latest release published after 3.9.3 by Cozy Vision Technologies once available on the WordPress plugin repository, consulting the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/sms-alert/vulnerability/wordpress-sms-alert-order-notifications-plugin-3-9-3-broken-authentication-vulnerability for the fixed version. Until the plugin can be upgraded, deactivate and remove the SMS Alert Order Notifications plugin (which will disable order SMS notifications), or place the affected endpoints behind a WAF rule that blocks unauthenticated requests to the plugin's AJAX/REST routes (trade-off: may break any legitimate front-end integrations that the plugin exposes). Restricting access to /wp-admin/admin-ajax.php and /wp-json/ paths via IP allowlisting on staging sites, and ensuring the plugin is not active on internet-exposed environments, are additional compensating controls.
