No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The MapSVG plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the SVGFile constructor in all versions up to, and including, 8.14.0 This is due to an incorrect conditional check that prevents file validation from taking place. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
