CyberRota Analysis
AI-GeneratedThe vulnerability affects the Nightingale platform's server-side request forgery (SSRF) protection within the http_fetch AI-agent tool, specifically in how it handles certain IPv6 address formats. An attacker can exploit this flaw to bypass security checks, potentially accessing sensitive internal services or metadata endpoints by encoding forbidden IPv4 addresses in unsupported IPv6 formats. Organizations using Nightingale should prioritize remediation to safeguard against potential unauthorized access to internal resources.

Original NVD Description
Nightingale (n9e), as of commit 8362cbe (main branch, confirmed 2026-08-27), contains a server-side request forgery vulnerability in the isPublicIP function in aiagent/tools/http.go, the SSRF guard for the http_fetch AI-agent tool. The function only unwraps standard IPv4-mapped (::ffff:a.b.c.d) IPv6 addresses before checking them against the forbidden-range list, and does not classify 6to4 (2002::/16), NAT64 (64:ff9b::/96, 64:ff9b:1::/48), or deprecated site-local (fec0::/10) addresses. On a dual-stack or NAT64-enabled host, an attacker able to supply a URL to the http_fetch tool can bypass the guard by encoding a forbidden IPv4 address (such as the cloud instance-metadata endpoint 169.254.169.254) in one of these IPv6 forms to reach internal or metadata services.
