CVE-2025-47562: MapSVG Code Injection Vulnerability

CVE-2025-47562 Overview

CVE-2025-47562 is a code injection vulnerability [CWE-94] affecting the RomanCode MapSVG plugin for WordPress. The flaw stems from improper control of code generation within the plugin, allowing an attacker to inject content that the application processes as code. All versions of MapSVG up to and including 8.5.34 are affected.

The vulnerability is network-exploitable and requires no authentication or user interaction. Successful exploitation results in a limited confidentiality impact on the affected WordPress site. The issue is tracked by Patchstack as a content injection vulnerability in the MapSVG plugin.

Critical Impact
Unauthenticated attackers can inject code into WordPress sites running vulnerable MapSVG plugin versions, potentially disclosing sensitive information.

Affected Products

RomanCode MapSVG plugin for WordPress
MapSVG versions from initial release through 8.5.34
WordPress sites with MapSVG installed and activated

Technical Details for CVE-2025-47562

Vulnerability Analysis

CVE-2025-47562 is classified under [CWE-94], Improper Control of Generation of Code. The MapSVG plugin processes user-supplied input in a way that allows attacker-controlled content to influence code or content generation on the server side. Patchstack categorizes the flaw as a content injection issue.

The vulnerability is exploitable over the network with low attack complexity. No privileges or user interaction are required, which makes exploitation attempts trivial to automate against WordPress sites that expose the plugin's functionality. The impact is scoped to confidentiality; integrity and availability are not directly affected according to the published CVSS vector.

The EPSS score at time of writing is 0.297%, placing this CVE in the 21.77 percentile for exploitation likelihood.

Root Cause

The root cause is insufficient validation and sanitization of input consumed by MapSVG code paths that generate or evaluate content dynamically. Because the plugin does not adequately restrict what input can influence code generation, an attacker can supply crafted values that are subsequently rendered or interpreted, resulting in injected content being served to users of the site.

Attack Vector

An unauthenticated remote attacker sends crafted HTTP requests to endpoints exposed by the MapSVG plugin on a target WordPress site. Because the input is not properly constrained, the payload influences the code or content generated by the plugin. This can be used to disclose information rendered in the context of the vulnerable application. Refer to the Patchstack WordPress Vulnerability Report for further technical details.

Detection Methods for CVE-2025-47562

Indicators of Compromise

Unexpected HTTP POST or GET requests to MapSVG plugin endpoints under /wp-content/plugins/mapsvg/ or MapSVG AJAX actions.
WordPress database entries or MapSVG map records containing script tags, template expressions, or unexpected server-side directives.
Web server access logs showing repeated requests from unauthenticated sources targeting MapSVG parameters.

Detection Strategies

Inventory WordPress installations and identify sites running MapSVG at version 8.5.34 or earlier.
Inspect MapSVG-stored map data for injected payloads, including HTML, JavaScript, or templating syntax not authored by site administrators.
Review web application firewall (WAF) logs for anomalous requests to MapSVG REST or admin-ajax handlers.

Monitoring Recommendations

Alert on modifications to MapSVG map records originating from unauthenticated sessions.
Monitor outbound requests from WordPress hosts for signs of data exfiltration following suspicious MapSVG requests.
Track plugin version drift across WordPress fleets to confirm patched builds are deployed.

How to Mitigate CVE-2025-47562

Immediate Actions Required

Identify all WordPress sites running MapSVG version 8.5.34 or earlier and prioritize them for remediation.
Update MapSVG to a fixed version once available from the vendor, following guidance in the Patchstack advisory.
Audit MapSVG-managed content for injected payloads and remove or restore affected records from a clean backup.

Patch Information

At the time of publication, the vulnerability is confirmed in MapSVG versions through 8.5.34. Administrators should consult the vendor and the Patchstack WordPress Vulnerability Report for the fixed release and apply it promptly through the WordPress plugin update mechanism.

Workarounds

Deactivate and remove the MapSVG plugin on sites where a fixed version cannot be deployed immediately.
Restrict access to MapSVG endpoints at the WAF or reverse proxy layer, blocking unauthenticated requests where feasible.
Enforce least privilege on WordPress accounts and review recent changes to MapSVG content for unauthorized modifications.

bash

# Identify MapSVG plugin version on a WordPress host using WP-CLI
wp plugin get mapsvg --field=version

# Deactivate MapSVG as a temporary workaround until a patched version is applied
wp plugin deactivate mapsvg
