Broken Access Control in Post SMTP WordPress Plugin Email Logs
CVE-2025-11833 is a critical broken access control vulnerability in the WordPress plugin "Post SMTP – Complete SMTP Solution with Logs, Alerts, Backup SMTP & Mobile App." In all versions up to and including 3.6.0, the plugin fails to enforce a capability/authorization check in the email log handler's __construct function, referenced in reporting as part of the PostmanEmailLogs flow. Because user permissions are not validated before access to email log functionality is initialized, unauthenticated attackers can directly access REST API endpoints that expose arbitrary emails logged by the plugin. Exposed messages can include sensitive content such as password reset emails containing reset links, enabling attackers to take over WordPress accounts, including administrator accounts.
