ThirstyAffiliates < 3.10.5 - Subscriber+ unauthorized image upload + CSRF

CVE-2022-0634

Summary

The ThirstyAffiliates WordPress plugin before 3.10.5 lacks authorization checks in the ta_insert_external_image action, allowing a low-privilege user (with a role as low as Subscriber) to add an image from an external URL to an affiliate link. Further the plugin lacks csrf checks, allowing an attacker to trick a logged in user to perform the action by crafting a special request.
