CVE-2026-6322 fast-uri vulnerable to host confusion via percent-encoded authority delimiters

fast-uri normalize decoded percent-encoded authority delimiters inside the host component and then re-emitted them as raw delimiters during serialization. A host that combined an allowed domain, an encoded at-sign, and a different domain was re-emitted with the at-sign as a raw userinfo separator...

CVE-2026-6322

CVE-2026-6322 affects the fast-uri package. The vuln lies in normalize(): it decodes percent-encoded authority delimiters inside the host and then re-emits them as raw delimiters during serialization. This can cause a host, which combines an allowed domain, an encoded at-sign, and a different dom...

Linux Distros Unpatched Vulnerability : CVE-2026-6321

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data wa...

CVE-2026-6322: Interpretation Conflict

fast-uri normalize decoded percent-encoded authority delimiters inside the host component and then re-emitted them as raw delimiters during serialization. A host that combined an allowed domain, an encoded at-sign, and a different domain was re-emitted with the at-sign as a raw userinfo separator...

fast-uri 安全漏洞

fast-uri is an open-source, dependency-free RFC 3986 URI parser and toolkit developed by Fastify. Versions of fast-uri 3.1.1 and earlier contained security vulnerabilities. These vulnerabilities stemmed from the normalize function decoding percent-encoded permission separators within the host...
