CVE-2025-24683: RSVP and Event Management SQL Injection

CVE-2025-24683 Overview

CVE-2025-24683 is a SQL Injection vulnerability in the WP Chill RSVP and Event Management plugin for WordPress. The flaw stems from improper neutralization of special elements in SQL commands [CWE-89]. It affects all plugin versions up to and including 2.7.14. An authenticated attacker with high privileges can inject arbitrary SQL statements through the affected plugin parameters. Successful exploitation can expose database contents and degrade application availability across other components sharing the database context. The vulnerability carries an EPSS probability of 0.564% as of June 2026.

Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, leading to disclosure of sensitive event registration data and potential impact on other site components.

Affected Products

WP Chill RSVP and Event Management plugin for WordPress
All versions from initial release through 2.7.14
WordPress installations with the rsvp plugin enabled

Technical Details for CVE-2025-24683

Vulnerability Analysis

The vulnerability resides in the WP Chill RSVP and Event Management plugin, which manages event registrations on WordPress sites. The plugin fails to properly sanitize or parameterize user-supplied input before incorporating it into SQL queries. This allows attackers to break out of the intended query context and append arbitrary SQL syntax.

The issue maps to [CWE-89], Improper Neutralization of Special Elements used in an SQL Command. Exploitation requires high privileges and no user interaction, with the attack delivered over the network. The scope is changed, meaning a successful attack affects resources beyond the vulnerable component.

While confidentiality impact is rated high and availability impact is low, integrity impact is reported as none. Attackers can read database contents including user records, event data, and any sensitive metadata stored by other plugins in the shared database.

Root Cause

The root cause is the construction of SQL queries using concatenated user input instead of prepared statements with bound parameters. WordPress provides the $wpdb->prepare() method for safe query construction, but the affected plugin code paths bypass this safeguard for at least one user-controlled parameter.

Attack Vector

An attacker authenticated to the WordPress instance with elevated privileges submits crafted input to a vulnerable plugin endpoint. The malicious payload contains SQL metacharacters and clauses such as UNION SELECT to extract data from arbitrary tables. Because the scope is changed, the injection can read data outside the plugin's intended tables, including the wp_users table and tokens stored by other plugins.

For technical specifics, see the Patchstack SQL Injection Vulnerability advisory.

Detection Methods for CVE-2025-24683

Indicators of Compromise

Web server access logs containing SQL metacharacters such as UNION, SELECT, --, or 0x in requests to plugin endpoints
Unusually long query strings or POST bodies targeting RSVP plugin admin URLs
Unexpected database errors logged by WordPress or MySQL referencing plugin tables
Authenticated admin sessions issuing requests with payloads containing encoded SQL syntax

Detection Strategies

Inspect WordPress access logs for requests to wp-admin/admin.php?page=rsvp* endpoints containing SQL keywords
Enable WordPress debug logging to capture database errors triggered by malformed queries
Deploy a web application firewall with SQL injection signatures tuned for WordPress plugin parameters
Correlate privileged account activity with anomalous database query patterns in MySQL general or slow query logs

Monitoring Recommendations

Monitor authenticated administrator account behavior for sudden bursts of plugin configuration requests
Alert on MySQL queries returning rows from wp_users or other sensitive tables outside normal application flow
Track plugin version inventory across WordPress sites and flag installations running rsvp2.7.14 or earlier
Review audit trails for newly created administrator accounts following suspicious plugin requests

How to Mitigate CVE-2025-24683

Immediate Actions Required

Update the WP Chill RSVP and Event Management plugin to a version newer than 2.7.14 once available from the vendor
Audit all WordPress administrator and editor accounts and remove unused or unnecessary privileged users
Rotate WordPress administrator credentials and database passwords if compromise is suspected
Restrict access to the WordPress admin interface using IP allowlists or VPN gating

Patch Information

At the time of NVD publication, the advisory indicates the vulnerability affects versions through 2.7.14. Administrators should monitor the Patchstack advisory and the WordPress plugin repository for an official fixed release and apply it without delay.

Workarounds

Deactivate and remove the RSVP and Event Management plugin until a patched version is installed
Deploy a web application firewall rule blocking SQL metacharacters in requests targeting plugin endpoints
Apply the principle of least privilege so administrator accounts are limited to trusted personnel only
Enforce multi-factor authentication on all WordPress accounts capable of accessing plugin functionality

bash

# Example WP-CLI commands to inventory and disable the affected plugin
wp plugin list --name=rsvp --fields=name,status,version
wp plugin deactivate rsvp
wp plugin delete rsvp
