What the vulnerability does
01Description
The Enable SVG, WebP, and ICO Upload plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 1.1.3. This is due to insufficient file type validation detecting ICO files, allowing double extension files with the appropriate magic bytes to bypass sanitization while being accepted as a valid ICO file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

An authenticated user with low privileges can upload malicious files to the site, potentially including executable code. This allows an attacker to run their own code on the site, read sensitive data, modify content, or disrupt service.
