GHSA-F65P-4M7J-42XC fast-uri vulnerable to server-side request forgery via malformed IPv6 normalization

Impact fast-uri does not validate the complete RFC 3986 grammar for bracketed IPv6 literals, so a malformed literal with invalid trailing text is silently truncated to a different valid IPv6 address with no error reported. For example, normalize'http://::not-valid/private' returns...

fast-uri: fast-uri: Server-side request forgery via malformed IPv6 normalization

A flaw was found in fast-uri, a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not fully validate the IPv6 grammar, allowing invalid trailing text in an authority to be silently discarded. This can lead to a malformed, attacker-controlled host being normalized into a...

EUVD-2026-50402

@fastify/rate-limit before 11.2.0 keys rate-limit buckets by the verbatim client IP string returned from request.ip. Because a single IPv6 client can control a large address range a /64 holds 2^64 distinct addresses and the same address has multiple valid textual representations, an IPv6 capable...

CVE-2026-44492 Axios: shouldBypassProxy does not recognize IPv4-mapped IPv6 addresses, allowing NO_PROXY bypass (incomplete fix for CVE-2025-62718)

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe...
