## Description

The RSVPMaker plugin for WordPress is vulnerable to unauthenticated SQL Injection due to missing SQL escaping and parameterization on user supplied data passed to a SQL query in the rsvpmaker-util.php file. This makes it possible for unauthenticated attackers to steal sensitive information from the database in versions up to and including 9.2.5.

## CrowdSec analysis

[CVE-2022-1453](https://euvd.enisa.europa.eu/vulnerability/CVE-2022-1453) is a critical SQL injection vulnerability in the RSVPMaker plugin for WordPress, affecting versions up to and including 9.2.5. This flaw allows unauthenticated attackers to inject malicious SQL queries via user-supplied data, potentially enabling them to steal sensitive information from the database or manipulate site data. The vulnerability arises from improper handling and lack of parameterization in SQL queries within the rsvpmaker-util.php file.

CrowdSec has been tracking this vulnerability and its exploits since 25th of March 2026.

Data from the CrowdSec community indicates that exploitation of CVE-2022-1453 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
CrowdSec network telemetry also shows that exploitation of CVE-2022-1453 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit the `/wp-json/rsvpmaker/v1/sked/` endpoint by injecting SQL commands into the `post_id` parameter, enabling unauthenticated access to sensitive database information on vulnerable WordPress sites.
