CVE-2026-70485 Open WebUI: Any authenticated user can reach internal services and cloud metadata via NAT64-encoded URLs

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.0, Open WebUI checked whether a user-supplied URL destination was globally routable by applying ipaddress.isglobal to the literal IPv6 address without examining IPv4 addresses embedded in...

ip-address: misclassification of IPv4-mapped/NAT64 IPv6 addresses can bypass SSRF and trust-boundary checks

Summary Address6's special-property checks misclassify IPv4-mapped ::ffff:0:0/96 and NAT64 well-known 64:ff9b::/96 IPv6 addresses. These checks classify an address by its IPv6 wrapper rather than by the IPv4 address it embeds, so isLoopback, isLinkLocal, isMulticast, and isUnspecified all return...

SUSE 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...

Name of the Vulnerable Software and Affected Versions ip-address versions 10.1.1 through 10.2.0 Description The library is susceptible to Server-Side Request Forgery SSRF due to the misclassification of IPv4-mapped and NAT64 IPv6 addresses. The Address6.getType function classifies addresses by...

CVE-2026-47695

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 ...

GHSA-XGCH-X3MX-CM3C safeurl is Missing IPv6 CIDR Ranges in Blocklist

The privateNetworks blocklist was found to be missing newly added CIDR ranges. More specifically, the following CIDR ranges were not being blocked: - 64:ff9b:1::/48: NAT64 local-use prefix RFC 8215 - 5f00::/16: Segment Routing SRv6 SIDs RFC 9602 - 3fff::/20: documentation prefix RFC 9637 -...

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...

GHSA-RJG7-R26H-CFP2 Koel: Full-read SSRF via podcast enclosure URL: isPublicHost() filter_var guard does not reject NAT64 (64:ff9b::/96) or 6to4 (2002::/16) IPv6-transition wrappers of internal IPv4

Summary Koel's outbound-URL guard App\Helpers\Network::isPublicHost classifies an IP as "public" using PHP's filtervar$ip, FILTERVALIDATEIP, FILTERFLAGNOPRIVRANGE | FILTERFLAGNORESRANGE. That flag set does not recognise IPv6 transition-address forms that embed a private/loopback/link-local IPv4:...
