DescriptionCVE.org

The Gravity SMTP plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.1.4. 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 uninstall and deactivate the plugin and delete plugin options. NOTE: This vulnerability is also exploitable via a Cross-Site Request Forgery vector.

AnalysisAI

Missing authorization in Gravity SMTP plugin for WordPress (versions ≤2.1.4) allows authenticated attackers with subscriber-level privileges to uninstall the plugin, deactivate functionality, and delete configuration options. Exploitable via direct API calls or CSRF attack vectors. Affects Gravity SMTP by Rocketgenius. Successful exploitation enables low-privileged users to disable critical SMTP mail delivery functionality and remove plugin settings without proper permission checks. No public exploit identified at time of analysis.

Technical ContextAI

Root cause: missing capability checks on administrative endpoints (CWE-862). CVSS vector PR:L confirms authenticated access required. CSRF vector (UI:N indicates no user interaction for direct exploitation) enables social engineering attack chains. Affects cpe:2.3:a:rocketgenius:gravity_smtp through version 2.1.4. Authorization bypass permits subscriber role to invoke privileged uninstall/deactivate operations.

RemediationAI

Vendor-released patch: upgrade to Gravity SMTP version 2.1.5 or later, which implements proper authorization controls for administrative actions. Gravity Forms release announcement confirms fix availability at https://www.gravityforms.com/brand-new-release-gravity-smtp-2-1-5/. Immediate mitigation: restrict WordPress subscriber role permissions via role manager plugins, implement Web Application Firewall rules blocking unauthorized admin-ajax.php requests from low-privilege users, audit user role assignments to minimize subscriber-level accounts. Post-upgrade verification: test that subscriber accounts cannot access plugin deactivation or settings deletion endpoints. Monitor access logs for suspicious administrative API calls from non-administrator sessions.
