What is CVE-2026-72777?

Next AI Draw.io prior to version 0.4.16 is susceptible to a server-side request forgery vulnerability within its POST /api/parse-url endpoint. The flaw arises from insufficient hostname validation, which relies on pattern matching instead of DNS resolution. This vulnerability allows unauthenticated attackers to manipulate hostnames that may bypass standard string validation checks, granting access to internal HTTP services. Consequently, attackers can exfiltrate sensitive information, including cloud metadata, by interfacing with internal network resources.

Affected Version(s)

next-ai-draw-io 0 <= 0.4.16

Exploit Proof of Concept (PoC)
