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 ...

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...

Name of the Vulnerable Software and Affected Versions fast-uri versions 2.4.2 through 2.4.4 fast-uri versions 3.1.3 through 3.1.5 fast-uri versions 4.0.1 through 4.1.2 Description fast-uri, a URI parser for Node.js, fails to consistently canonicalize hosts to ASCII form when processing...

CVE-2026-75899: Double Decoding of the Same Data

fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authority recomposition, so a single call to normalize or resolve can turn nested percent-encoded input into a different network destination such...

Keycloak: Open redirect when using wildcard valid redirect URIs in Keycloak

A flaw was found in Keycloak's URL validation logic during redirect operations. By crafting a malicious request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading to the exposure of sensitive information within the domain or facilitating further...
