stoatchat before 0.14.0 contains a server-side request forgery (SSRF) vulnerability that allows unauthenticated network-accessible attackers to bypass the DNS-based IP blocklist by exploiting incomplete address validation in the url_is_blacklisted function, which inspects only the first resolved address while the underlying HTTP client iterates all cached addresses.
