CVE-2025-47775Public exploit

Workflow data exfiltration via unchecked TCP DNS

Published May 14, 2025 · Updated May 14, 2025

Information disclosure in Bullfrog before 0.8.4 allows local users to exfiltrate workflow data through DNS over TCP. The packet-processing path recognizes DNS only when gopacket exposes a DNS layer, so TCP-encapsulated DNS bypasses domain-policy checks. A workflow step running after Bullfrog in block mode can send sensitive data in TCP DNS queries to a disallowed domain, bypassing the egress sandbox.
