CVE-2026-73530 Flyto2 Core < 2.28.0 SSRF Guard Bypass via is_private_ip()

Flyto2 Core before 2.28.0 contains a server-side request forgery guard bypass vulnerability that allows attackers to reach internal services by supplying URLs using the unblocked IPv6 address :: which the kernel routes to loopback identically to 0.0.0.0. Attackers can submit requests or trigger 3...

CVE-2026-73530

The CVE concerns Flyto2 Core prior to 2.28.0, where SSRF guard bypass is possible via unblocked IPv6 address :: that kernels treat as loopback akin to 0.0.0.0. Attackers can cause requests or 302 redirects through http.get, http.request, and http.batch to reach services bound to IPv6 loopback, by...

CVE-2026-49857

auth-fetch-mcp is an MCP server that lets AI assistants fetch content from authenticated web pages. Version 3.0.1 implements SSRF protection in assertSafeUrl src/security.ts to block requests to private and loopback addresses. However, the isPrivateV6 function fails to detect IPv4-mapped IPv6...

CVE-2026-49857

auth-fetch-mcp has an SSRF protection bypass via IPv4-mapped IPv6 loopback. The root cause is in isPrivateV6() handling of hex-normalized IPv4-mapped addresses; input like http://[::ffff:127.0.0.1]:PORT/ becomes http://[::ffff:7f00:1]:PORT/ and net.isIPv4 returns false, allowing requests to priva...
