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...

CVE-2026-110306 fast-uri vulnerable to URI scheme spoofing via percent-encoded scheme decoding

fast-uri is a dependency-free RFC 3986 URI parser and serializer for Node.js. In versions before 2.4.8, from 3.0.0 through 3.1.8, and from 4.0.0 through 4.2.2, fast-uri percent-decodes the scheme component with the legacy global unescape function before validating it, so an input whose decoded...

NPM: fast-uri vulnerable to host confusion via percent-encoded scheme normalization

fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

fast-uri: fast-uri: URI parsing flaw enables server-side request forgery and redirects

A flaw was found in fast-uri, a software component used for parsing Uniform Resource Identifiers URIs in Node.js applications. This vulnerability arises from an issue in how fast-uri processes the scheme part of a URI, specifically when it contains special characters that are percent-encoded. An...

CVE-2026-76172

fast-uri is a URI parser for Node.js. During parsing it runs a legacy decoding pass over the scheme component and never re-escapes the result, and serialization writes the scheme back out verbatim, unlike the host component which is re-escaped. As a result an input whose scheme carries...
