CVE-2025-54669: MapSVG WordPress Plugin SQLi Vulnerability

CVE-2025-54669 Overview

CVE-2025-54669 is a SQL injection vulnerability in the RomanCode MapSVG WordPress plugin. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. It affects all MapSVG plugin versions up to and including 8.7.4. Unauthenticated attackers can inject crafted SQL statements through the plugin over the network without user interaction. Successful exploitation can expose sensitive database content and affect application availability. Patchstack tracks this issue in its WordPress plugin vulnerability database.

Critical Impact

Unauthenticated network-based SQL injection in a widely deployed WordPress plugin enables attackers to read sensitive database records and disrupt plugin functionality.

Affected Products

• RomanCode MapSVG WordPress plugin versions up to and including 8.7.4
• WordPress sites running the vulnerable mapsvg plugin
• Any deployment exposing the plugin endpoints to untrusted networks

Discovery Timeline

Technical Details for CVE-2025-54669

Vulnerability Analysis

The vulnerability resides in the MapSVG plugin's handling of user-supplied input that flows into SQL queries. The plugin fails to properly neutralize special characters before incorporating data into database statements. An attacker can append SQL syntax to a vulnerable parameter and alter the structure of the executed query. The CWE-89 classification confirms the root issue is missing or insufficient input sanitization at the database layer.

Because the attack vector is network-based and requires no authentication or user interaction, exploitation can be automated against exposed WordPress sites. The scope is changed, meaning a successful injection can affect resources beyond the vulnerable component itself. Confidentiality impact is high, while availability impact is low and integrity is not directly affected per the CVSS vector.

Root Cause

The root cause is improper neutralization of special elements in SQL commands within the MapSVG plugin code path. Input received through plugin requests is concatenated into SQL queries rather than being processed through parameterized statements or properly escaped using WordPress database helpers such as $wpdb->prepare(). This pattern allows attacker-controlled syntax to be interpreted as part of the query.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP requests to a WordPress site running MapSVG 8.7.4 or earlier. The malicious payload is delivered through a vulnerable plugin parameter that is concatenated into a backend SQL statement. The injected statement runs with the privileges of the WordPress database user. Attackers commonly use this access to enumerate tables, exfiltrate wp_users records and password hashes, and stage further compromise of the site.

No public proof-of-concept exploit has been published in the references at the time of writing. Refer to the Patchstack WordPress Plugin Vulnerability advisory for technical details.

Detection Methods for CVE-2025-54669

Indicators of Compromise

• HTTP requests to MapSVG plugin endpoints containing SQL meta-characters such as ', --, UNION, SELECT, or SLEEP(
• Unexpected outbound database errors or stack traces in WordPress debug.log referencing plugin files under wp-content/plugins/mapsvg/
• Anomalous read activity against wp_users, wp_usermeta, or wp_options tables
• New or modified administrator accounts created shortly after suspicious plugin traffic

Detection Strategies

• Inspect web server access logs for requests targeting MapSVG plugin routes with encoded SQL syntax in query parameters or POST bodies
• Deploy a Web Application Firewall (WAF) ruleset that flags SQL injection signatures against /wp-admin/admin-ajax.php and plugin REST endpoints
• Correlate WordPress audit logs with database query logs to identify queries containing unbalanced quotes or stacked statements

Monitoring Recommendations

• Enable MySQL or MariaDB general query logging on at-risk sites during incident response to capture injected payloads
• Alert on spikes in 500-series responses or long-running queries originating from MapSVG plugin handlers
• Monitor for changes to plugin files, WordPress salts, and administrator accounts on systems running MapSVG

How to Mitigate CVE-2025-54669

Immediate Actions Required

• Update the MapSVG plugin to a version later than 8.7.4 as soon as a fixed release is published by RomanCode
• If no patched version is available, deactivate and remove the MapSVG plugin from production WordPress sites
• Rotate WordPress database credentials and administrator passwords if exploitation is suspected
• Review user accounts and scheduled tasks for unauthorized modifications

Patch Information

Consult the Patchstack advisory for the MapSVG plugin for the current fixed version and vendor remediation guidance. Apply the vendor patch in a staging environment before promoting to production.

Workarounds

• Restrict access to WordPress admin and AJAX endpoints by source IP where feasible
• Deploy virtual patching rules through a WAF to block SQL injection payloads targeting MapSVG parameters
• Enforce least-privilege on the WordPress database user, removing rights such as FILE, CREATE USER, and cross-database access
• Disable the plugin on sites that do not actively require MapSVG functionality

# Configuration example: disable the MapSVG plugin using WP-CLI
wp plugin deactivate mapsvg
wp plugin delete mapsvg

# Verify removal
wp plugin list --status=active | grep -i mapsvg
