fast-uri vulnerable to URI scheme spoofing via percent-encoded scheme decoding...

GHSA-W74X-V6F9-J3XG fast-uri vulnerable to URI scheme spoofing via percent-encoded scheme decoding

Impact fast-uri percent-decodes the scheme component with the legacy global unescape before validating it, so an input whose decoded scheme is a valid but dangerous token is emitted as a live scheme. RFC 3986 section 3.1 does not allow percent-encoding in a scheme, so no RFC or WHATWG parser trea...

GHSA-WJR9-J795-JXCR fast-uri vulnerable to host confusion via unchecked WHATWG host canonicalization

Impact fast-uri versions = 2.4.2, = 3.1.3, = 4.0.1, = 4.2.2 can silently rewrite the host of an HTTP-family URL http, https, ws, wss, or any scheme with domainHost: true. For those schemes canonicalizeHost passes the parsed host to the WHATWG URL parser and adopts its .hostname without checking...

GHSA-333X-W4R6-6CRP fast-uri vulnerable to scheme injection via an unescaped first-segment colon in suffix references

Impact fast-uri's serialize, normalize, and resolve, when called with the non-default option reference: 'suffix' on a reference that has no authority, emit a relative reference whose first path segment contains a bare colon without escaping it. RFC 3986 section 3.3 requires the first segment of a...
