At a glance
CVE-2022-1054 is a medium-severity Missing Authorization vulnerability in the RSVP and Event Management WordPress plugin, affecting versions <= 2.7.7. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.7.8; sites on affected versions should update now. Disclosed April 2022, reported by Daniel Ruf.
Vulnerability Overview
The RSVP and Event Management Plugin WordPress plugin before 2.7.8 does not have any authorisation checks when exporting its entries, and has the export function hooked to the init action. As a result, unauthenticated attackers could call it and retrieve PII such as first name, last name and email address of user registered for events
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in RSVP and Event Management <= 2.7.7 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For RSVP and Event Management the fix is 2.7.8: builds <= 2.7.7 are affected, anything from 2.7.8 onward is not.
Remediation
Update to version 2.7.8, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: RSVP and Event Management 2.7.8 closes this, and updating the plugin is the step that ends it.
