CVE-2021-24371 is a low-severity vulnerability rated 2.7/10 on the CVSS scale. 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.. EPSS estimates a 1.01% chance of exploitation in the next 30 days.
