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...

SUSE 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...

During parsing it runs a legacy decoding pass over the scheme component and never re-escapes the result, and serialization...

CVE-2026-76172

fast-uri , a URI parser for Node.js, is vulnerable to host confusion via percent-encoded scheme normalization . The root cause is a legacy decoding pass applied to the scheme component that is never re-escaped before serialization, causing a mismatch between the parsed host (undefined) and the re...
