Description
The Form Maker by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via front-end form file uploads in versions 1.15.36 up to, and including, 1.15.49. This is due to an incomplete check of uploaded SVG file content that can be bypassed with whitespace padding. This makes it possible for unauthenticated attackers to upload SVG files containing arbitrary web scripts through a form with a file upload field. The scripts execute whenever a user accesses the uploaded file.
