CVE-2026-54450

ToolHive is a Go utility for deploying and managing Model Context Protocol (MCP) servers. Prior to v0.29.1 , the SSRF guard networking.IsPrivateIP in pkg/networking/utilities.go omits the IPv6 NAT64 prefixes 64:ff9b::/96 and 64:ff9b:1::/48, causing NAT64-encoded private addresses to be classified...

CVE-2026-54450 ToolHive: SSRF guard misses IPv6 NAT64 ranges (64:ff9b::/96, 64:ff9b:1::/48), allowing metadata/internal access behind a NAT64 gateway

GHSA-PPH6-VFJV-VPJW ToolHive: SSRF guard misses IPv6 NAT64 ranges (64:ff9b::/96, 64:ff9b:1::/48), allowing metadata/internal access behind a NAT64 gateway

Summary ToolHive's hand-rolled private/reserved-IP SSRF guard networking.IsPrivateIP in pkg/networking/utilities.go does not recognize the IPv6 NAT64 address ranges — the well-known prefix 64:ff9b::/96 RFC 6052 and the RFC 8215 local-use prefix 64:ff9b:1::/48. As a result, an address such as...
