Update, patch or deactivate.
Update Product Addons and Product Options With Custom Fields to 1.6.15 or later. Remove untrusted SVG files from upload locations and, until patched, reject SVG and SVGZ uploads at the web server or application boundary.

Technical description
The Product Addons and Product Options With Custom Fields WordPress plugin before 1.6.15 does not restrict an unauthenticated file-upload endpoint and accepts SVG files that are stored and served inline, allowing an unauthenticated attacker to upload a malicious SVG whose embedded script executes in the session of any user (such as an administrator) who later opens the file.
