Miniflux 2.3.0 through 2.3.3 contains a server-side request forgery vulnerability that allows authenticated users to reach internal addresses by setting a feed's proxy_url. Attackers can point proxy_url at loopback or internal hosts, bypassing FETCHER_ALLOW_PRIVATE_NETWORKS checks to probe internal ports and send proxy-style requests to internal services.
