CVE-2021-24371: Carrcommunications Rsvpmaker

Low severity, CVSS 2.7. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• Carrcommunications Rsvpmaker: before 8.7.3 (fixed in 8.7.3)
