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 gatewayCVE-2026-54450 0 ToolHive's SSRF protection function fails to recognize IPv6 NAT64 address ranges (64:ff9b::/96 and 64:ff9b:1::/48) as private, allowing connections to internal or link-local addresses behind a NAT64 gateway. This flaw enables an attacker controlling a URL parameter in the OAuth authorization server to bypass SSRF guards and cause ToolHive to connect to internal metadata or other protected addresses. The vulnerability primarily results in blind internal reachability probing rather than direct data leakage, as the attacker cannot control or view responses. The issue affects all ToolHive versions prior to 0.29.1. No patch information is provided, so patch status is unconfirmed.
