CVE-2026-54272

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6 addresses. Address6.getType classifies an address by matching it against a table of known IPv6...

CVE-2026-47695 CC-Tweaked has an SSRF Protection Bypass with NAT64

CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game. Prior to version 1.119.0, CC-Tweaked's HTTP API http.request, http.websocket blocks requests to private network ranges to prevent server-side request forgery SSRF. This protection can be bypassed ...

CVE-2026-47695

CC-Tweaked has an SSRF protection bypass via NAT64. Before version 1.119.0, the HTTP API endpoints (http.request, http.websocket) could be tricked into reaching internal IPv4 services by supplying a NAT64 address in the URL (example: http://[64:ff9b::]/). The NAT64 prefix 64:ff9b::/96 is not reco...

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...

Name of the Vulnerable Software and Affected Versions ToolHive versions prior to 0.29.1 Description ToolHive contains a Server-Side Request Forgery SSRF issue where the private IP guard in pkg/networking/utilities.go fails to recognize IPv6 NAT64 address ranges, specifically the well-known prefix...

GHSA-794R-5RP2-FPG8 flyto-core has SSRF guard bypass via IPv6 transition addresses (IPv4-mapped / 6to4 / NAT64) in validate_url_ssrf

Summary flyto-core's SSRF protection validateurlssrf / isprivateip in src/core/utils.py blocks private and metadata destinations by resolving the host and testing the resulting IP for membership in a hardcoded PRIVATEIPRANGES list. That list contains only the native RFC 1918 / loopback / link-loc...

CVE-2026-44430 MCP Registry: Unauthenticated SSRF: HTTP namespace verification dials 6to4 / NAT64 / site-local IPv6 addresses, bypassing private-address allowlist

The MCP Registry provides MCP clients with a list of MCP servers, like an app store for MCP servers. Prior to 1.7.7, the Registry's HTTP-based namespace verification POST /v0/auth/http, POST /v0.1/auth/http uses safeDialContext internal/api/handlers/v0/auth/http.go:67-110 to refuse dialling...

CVE-2026-8369 Improper Input Validation in OpenThread NAT64 Translator

Improper Input Validation in the NAT64 translator in The OpenThread Authors OpenThread before commit 26a882d on all platforms allows an attacker on the adjacent IPv4 network to inject corrupted IPv6 packets into the Thread mesh or bypass security checks via crafted IPv4 packets with options...

The vulnerability affects the implementation of NAT64 technology for Juniper Networks’ MS-MIC and MS-MPC routers, as well as Junos OS-based MX routers. This allows attackers to cause service interruptions.

The vulnerability of NAT64 technology implemented in Juniper Networks’ MS-MIC and MS-MPC routers for Junos OS operating systems is related to incorrect calculation of buffer size when processing IPv6 and IPv4 packets. Exploiting this vulnerability allows a malicious actor to cause service failure...
