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

Summary Open WebUI fetches user-supplied URLs on the server for RAG URL ingestion, URL-to-markdown conversion and web-search content retrieval, and decides whether a destination is allowed by asking whether its IP address is globally routable. That test operates on the literal IPv6 address and do...

Access Control Bypass

Overview Affected versions of this package are vulnerable to Access Control Bypass in the dashboard process. An attacker can take control of all dashboard routing by claiming the Host through NAT as an authenticated user. Remediation Upgrade github.com/nezhahq/nezha/model to version 2.1.0 or...

GHSA-86M8-88FQ-XFXP Gotenberg has an SSRF deny-list bypass in IsPublicIP via IPv6 6to4 / NAT64 / site-local prefixes

Summary IsPublicIP in pkg/gotenberg/outbound.go incorrectly classifies IPv6 6to4 / NAT64 / deprecated site-local addresses as public IPs, allowing an unauthenticated attacker to reach internal destinations e.g., cloud metadata services at 169.254.169.254 via a single crafted DNS AAAA record. This...

CVE-2026-8369

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...

CVE-2026-24935 An improper certificate validation vulnerability was found in a third-party NAT traversal module.

A third-party NAT traversal module fails to validate SSL/TLS certificates when connecting to the signaling server. While subsequent access to device services requires additional authentication, a Man-in-the-Middle MitM attacker can intercept or redirect the NAT tunnel establishment. This could...

CVE-2025-53856
