    CVE-2021-47830

    GetSimple CMS My SMTP Contact Plugin 1.1.1 contains a cross-site request forgery (CSRF) vulnerability. Attackers can craft a malicious webpage that, when visited by an authenticated administrator, can change SMTP configuration settings in the plugin. This may allow unauthorized changes but does not directly enable remote code execution.
