Summary

Wormhole.app as deployed before 2026-08-22 misconfigures the coturn TURN server and does not properly restrict TCP relay peers, allowing an unauthenticated attacker to access instance metadata or to source TCP connections from the Wormhole relay's IP.

Risk Assessment

An attacker can access sensitive instance metadata or use the relay IP for attacks, potentially compromising confidentiality and integrity of the infrastructure.

Recommendation

Update Wormhole.app to the latest version and fix the coturn configuration to properly restrict TCP relay peers and secure metadata access.
