CVE-2026-48874: GamiPress SQL Injection Vulnerability

CVE-2026-48874 Overview

CVE-2026-48874 is a SQL injection vulnerability in the GamiPress WordPress plugin affecting versions up to and including 7.8.7. The flaw allows authenticated users with Subscriber-level privileges to inject malicious SQL into database queries. Because Subscriber is the lowest WordPress role, exploitation requires only minimal account access on a vulnerable site.

The vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command). Successful exploitation can disclose sensitive database contents, including user data, post metadata, and gamification records. The scope is rated as changed, indicating impact beyond the vulnerable component itself.

Critical Impact
Authenticated Subscriber accounts can extract arbitrary data from the WordPress database and degrade site availability through crafted SQL queries against GamiPress endpoints.

Affected Products

GamiPress plugin for WordPress, versions <= 7.8.7
WordPress installations exposing GamiPress functionality to authenticated users
Sites permitting open Subscriber registration with GamiPress enabled

Technical Details for CVE-2026-48874

Vulnerability Analysis

The vulnerability is a SQL injection flaw in GamiPress version 7.8.7 and earlier. An attacker with Subscriber privileges can submit crafted input to a GamiPress request handler that is concatenated into a SQL statement without proper sanitization or parameterization. The database executes the attacker-controlled fragment as part of the original query.

The attack vector is network-based and the attack complexity is low. Privileges required are limited to a Subscriber account, which many WordPress sites grant freely through open registration. No user interaction is needed after authentication, and the scope change indicates the impact extends beyond the GamiPress plugin to the broader WordPress database.

Root Cause

The root cause is missing input neutralization in a GamiPress request handler accessible to authenticated low-privilege users. User-supplied parameters reach a $wpdb query without being passed through prepare() or escaped with esc_sql(). WordPress core sanitization is bypassed because the plugin builds the query string directly from request input.

Attack Vector

An attacker first obtains a Subscriber account on the target site, either through open registration or by compromising existing credentials. The attacker then issues an authenticated HTTP request to a vulnerable GamiPress endpoint with a payload designed to break out of the intended SQL clause. Time-based or UNION-based techniques can be used to exfiltrate data row by row.

No public proof-of-concept code has been published. Technical specifics are documented in the Patchstack WordPress Vulnerability Report.

Detection Methods for CVE-2026-48874

Indicators of Compromise

HTTP requests to GamiPress endpoints containing SQL syntax such as UNION SELECT, SLEEP(, BENCHMARK(, or stacked semicolons
Authenticated requests from Subscriber-role accounts producing unusual database query latency
Web server logs showing repeated parameterized requests to /wp-admin/admin-ajax.php with action= values tied to GamiPress
Unexpected reads against wp_users, wp_usermeta, or GamiPress custom tables originating from PHP worker processes

Detection Strategies

Inspect WordPress access logs for encoded SQL keywords in query strings and POST bodies targeting GamiPress actions
Enable MySQL general query logging temporarily to identify malformed or anomalously large SELECT statements from the WordPress user
Deploy a web application firewall rule set with signatures for SQL injection patterns scoped to /wp-admin/admin-ajax.php and GamiPress REST routes

Monitoring Recommendations

Alert on creation of new Subscriber accounts followed within minutes by requests to GamiPress endpoints
Monitor outbound database egress volume from the WordPress host for spikes consistent with bulk data extraction
Track failed login attempts and successful authentications from foreign IP ranges against WordPress sites running GamiPress

How to Mitigate CVE-2026-48874

Immediate Actions Required

Update GamiPress to a version newer than 7.8.7 as soon as a patched release is available from the vendor
Disable open user registration on WordPress sites where Subscriber accounts are not required for business function
Audit existing Subscriber accounts and remove those that are inactive or unrecognized
Place the WordPress site behind a web application firewall with SQL injection protections enabled

Patch Information

Refer to the Patchstack WordPress Vulnerability Report for current patch status. Administrators should upgrade GamiPress to the latest version distributed through the WordPress plugin repository once released.

Workarounds

Restrict access to GamiPress AJAX and REST endpoints at the web server or WAF layer until a patch is applied
Temporarily deactivate the GamiPress plugin on sites where gamification functionality is not business-critical
Limit the database user account used by WordPress to the minimum privileges necessary, removing FILE and unneeded write grants
Enforce strong password policy and multi-factor authentication for all WordPress accounts including Subscribers

bash

# Configuration example: restrict GamiPress AJAX actions at the web server
# nginx snippet to block unauthenticated and suspicious requests
location = /wp-admin/admin-ajax.php {
    if ($arg_action ~* "^gamipress_") {
        # require an authenticated WordPress session cookie
        if ($http_cookie !~* "wordpress_logged_in_") {
            return 403;
        }
    }
    include fastcgi_params;
    fastcgi_pass php_upstream;
}
