CVE-2024-9544
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe MapSVG plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 8.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe MapSVG WordPress plugin fails to properly sanitize SVG file uploads, allowing authenticated attackers with Contributor-level or higher permissions to embed malicious JavaScript within SVG files. Since SVG files are served as static content, the embedded scripts execute in the browsers of users who access these files, creating a stored XSS vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify MapSVG plugin is installedLog in to WordPress admin panel, go to Plugins > Installed Plugins, and look for MapSVG in the list. Alternatively, check the /wp-content/plugins/ directory for a mapsvg folder.Affected if MapSVG plugin is present on the WordPress site
-
Check installed MapSVG versionIn WordPress admin, find MapSVG in the Plugins list and note the version number displayed. Compare this version against version 8.6.5.Affected if The installed version is lower than 8.6.5 (the fixed version)
-
Confirm SVG upload feature is enabledNavigate to MapSVG > Settings in WordPress admin and look for SVG upload or file upload settings. Check if the SVG file type is allowed or if there is an option to enable SVG uploads.Affected if SVG uploads are enabled in the MapSVG settings
-
Inspect uploaded SVG files for malicious contentCheck the /wp-content/uploads/mapsvg/ directory (or similar upload paths used by MapSVG) for SVG files. Open any SVG files in a text editor and look for <script> tags, javascript: URLs, or event handler attributes like onload, onerror, onclick.Affected if SVG files contain embedded JavaScript, <script> tags, or event handlers that could execute in a user's browser
A user is affected if MapSVG plugin versions below 8.6.5 are installed with SVG upload functionality enabled, allowing potentially malicious SVG files to be served to browsers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the MapSVG plugin to version 8.6.5 or later if available; otherwise disable SVG uploads or implement server-side SVG sanitization (e.g., using a library like DOMPurify) before serving files.
