GHSA-5JGF-P345-68V8 fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

Impact fast-uri canonicalizes a host to its ASCII form only when the input carries an explicit scheme. When resolve resolves a scheme-relative reference //host/ against a scheme-bearing base, it still emits the host verbatim even though the effective scheme is known, so re-parsing the resolved UR...

fast-uri: fast-uri: Host confusion via skipped IDN canonicalization

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...

Linux Distros Unpatched Vulnerability : CVE-2026-75931

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference...

Interpretation Conflict

Overview fast-uri is a Dependency-free RFC 3986 URI toolbox Affected versions of this package are vulnerable to Interpretation Conflict in resolve through the resolve process in index.js. An attacker can make an application resolve a scheme-relative reference such as //host/ against a...

CVE-2026-75931

fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is returned with its host verbatim and no error set. As a result fast-uri's own entry points disagr...

CVE-2026-75931

fast-uri , a URI parser for the Node.js ecosystem, is vulnerable to host confusion and policy bypass (CVSS 3.1: 7.5 HIGH ). The root cause is that the host is canonicalized to ASCII form only when the input carries an explicit scheme; scheme-relative references (host preceded by //) are returned ...
