# CVE-2021-24371: RSVPMaker \< 8.7.3 - Authenticated (admin+) SSRF

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 8.7.3
- Published: 2021-08-02 · Updated: 2024-08-03

## Affected

- Unknown RSVPMaker: from 8.7.3, fixed in 8.7.3

## 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.

## What to do
