Sirv < 7.2.3 - Missing Authorization to Arbitrary Options Update

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_dismiss_notice() function in all versions up to, and including, 7.2.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to update arbitrary options which could lead to privilege escalation.
