Official description

The Image Optimizer, Resizer and CDN – Sirv plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to insufficient validation on the filename parameter of the sirv_upload_file_by_chunks() function and lack of in all versions up to, and including, 7.3.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary option values on the WordPress site.
