CVE-2026-1771

HIGH

MapSVG <= 8.14.0 - Authenticated (Administrator+) Arbitrary File Upload via '/mapsvg/v1/svgfile' Endpoint

Title source: cna

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.
