fast-uri: fast-uri: Host confusion vulnerability via backslash in URI authority

A flaw was found in fast-uri. This vulnerability arises because fast-uri incorrectly parses Uniform Resource Identifiers URIs when a backslash is used in place of a forward slash to introduce the authority component. This discrepancy with Node's native WHATWG URL parser can lead to host confusion...

CVE-2026-18446

CVE-2026-18446 affects the fast-uri library prior to versions 4.1.2, 3.1.5, and 2.4.4 .

GHSA-V2HH-GCRM-F6HX fast-uri vulnerable to host confusion via literal backslash authority delimiter

Impact fast-uri v4.1.0 and earlier do not treat a literal backslash U+005C as an authority delimiter. Node's native WHATWG URL used by fetch, undici, and Node's http/https clients normalizes \ to / for special schemes http, https, ws, wss, ftp, file, so the two parsers extract different hosts fro...

DEBIAN-CVE-2026-6321

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications...
