Fast-uri Vulnerable To Improper Path Equivalence In Relative Reference Normalization

Impact "fast-uri"'s "normalize" and "serialize" apply RFC 3986 dot-segment removal "removedotsegments" to the path of a relative-path reference. RFC 3986 section 5.2.4 defines that algorithm only for the merged target path during resolution, not for the reference itself, so applied to the referen...

CVE-2026-110725

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, when serialize, normalize, or resolve are called with the non-default option reference set to suffix on a reference that has no authority...

CVE-2026-75931 fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

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 ...
