Vulnerability Title
Image Optimizer, Resizer and CDN – Sirv <= 7.2.7 - Missing Authorization to Authenticated (Contributor+) Arbitrary File Upload
Vulnerability Description
The Image Optimizer, Resizer and CDN – Sirv plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'sirv_save_prevented_sizes' function in all versions up to, and including, 7.2.7. This makes it possible for authenticated attackers, with Contributor-level access and above, to exploit the 'sirv_upload_file_by_chunks_callback' function, which lacks proper file type validation, allowing attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
