CVE-2021-24371 Information

Description

The Import feature of the RSVPMaker WordPress plugin before 8.7.3 (/wp-admin/tools.php?page=rsvpmaker_export_screen) takes an URL input and calls curl on it without first validating it to ensure it’s a remote one. As a result a high privilege user could use that feature to scan the internal network via a SSRF attack.
