CVE-2025-32684: MapSVG Authorization Bypass Vulnerability

CVE-2025-32684 Overview

CVE-2025-32684 is a missing authorization vulnerability in the RomanCode MapSVG Lite Interactive Vector Maps plugin for WordPress. The flaw affects all versions from initial release through 8.6.4. The plugin fails to enforce proper access control checks on certain functionality, allowing authenticated users with low privileges to access resources or actions intended for higher-privileged roles. The weakness is categorized under [CWE-862] (Missing Authorization). Patchstack published the advisory referencing the broken access control condition in the plugin.

Critical Impact
Authenticated attackers with minimal privileges can bypass authorization checks and interact with plugin functionality across a scope boundary, exposing configuration and map data on affected WordPress installations.

Affected Products

RomanCode MapSVG Lite Interactive Vector Maps plugin for WordPress
All versions from initial release through and including 8.6.4
WordPress sites running the vulnerable mapsvg-lite-interactive-vector-maps plugin

Technical Details for CVE-2025-32684

Vulnerability Analysis

The vulnerability stems from missing authorization enforcement in the MapSVG Lite plugin. The plugin exposes actions or endpoints that do not verify whether the calling user holds the required capability. An authenticated user, including a low-privileged role such as Subscriber, can invoke these endpoints and act on functionality reserved for administrators.

Because the CVSS scope is marked as changed, the impact extends beyond the vulnerable plugin component to affect resources managed by the broader WordPress instance. Confidentiality impact is limited, while integrity and availability are not directly affected according to the published metrics.

Root Cause

The root cause is the absence of capability checks (for example, current_user_can()) and/or nonce validation on handlers registered by the plugin. WordPress plugins that expose admin-ajax.php actions or REST routes must explicitly verify the caller's role and intent. MapSVG Lite versions up to 8.6.4 omit at least one such check, resulting in broken access control ([CWE-862]).

Attack Vector

Exploitation requires network access to the WordPress site and an authenticated session with low privileges. No user interaction is required. An attacker registers or compromises a low-privilege account, then issues crafted HTTP requests to the plugin's unprotected endpoints. Because the vulnerability is exposed over the network and requires only low complexity, mass scanning of WordPress installations running the plugin is feasible.

No public proof-of-concept, exploit code, or CISA KEV listing is currently associated with this CVE. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2025-32684

Indicators of Compromise

Unexpected HTTP POST requests to admin-ajax.php containing MapSVG-related action parameters from low-privileged user sessions.
Requests to plugin-specific REST endpoints under /wp-json/ associated with mapsvg-lite-interactive-vector-maps originating from newly created accounts.
Modification, creation, or enumeration of MapSVG map objects performed by non-administrator users in WordPress audit logs.

Detection Strategies

Inventory WordPress sites and identify installations of the mapsvg-lite-interactive-vector-maps plugin at version 8.6.4 or earlier.
Correlate web server access logs with WordPress user role data to identify low-privilege accounts invoking plugin actions.
Deploy a web application firewall rule set that flags MapSVG plugin endpoints being called by users lacking manage_options capability.

Monitoring Recommendations

Enable WordPress activity logging to capture role, action, and endpoint metadata for plugin requests.
Alert on bulk registration of Subscriber accounts followed by requests to plugin admin endpoints.
Monitor for outbound changes to MapSVG configuration and map data that occur outside administrator sessions.

How to Mitigate CVE-2025-32684

Immediate Actions Required

Update the RomanCode MapSVG Lite Interactive Vector Maps plugin to a version later than 8.6.4 once the vendor publishes a fixed release.
Audit existing WordPress user accounts and remove or suspend unexpected low-privilege registrations.
Restrict user registration on WordPress sites that do not require public sign-ups by disabling the "Anyone can register" setting.

Patch Information

Refer to the Patchstack Vulnerability Report for vendor patch status and upgrade guidance. The advisory identifies all versions through 8.6.4 as vulnerable. Administrators should track the plugin's changelog on the WordPress Plugin Directory for the release that remediates the missing authorization check.

Workarounds

Deactivate and remove the MapSVG Lite plugin until a patched version is installed if interactive maps are not business-critical.
Deploy web application firewall rules that block unauthenticated and low-privileged access to plugin AJAX and REST endpoints.
Enforce least-privilege on WordPress roles and require multi-factor authentication for any account with elevated capabilities.

bash

# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate mapsvg-lite-interactive-vector-maps
wp plugin delete mapsvg-lite-interactive-vector-maps

# Confirm no residual plugin files remain
wp plugin list --status=active | grep -i mapsvg
