NPM: fast-uri vulnerable to host confusion via percent-encoded authority delimiters

NPM: fast-uri vulnerable to host confusion via percent-encoded authority delimiters vulnerability discovered by ? in WordPress Npm fast-uri versions = 3.1.1...

GHSA-V39H-62P7-JPJC fast-uri vulnerable to host confusion via percent-encoded authority delimiters

Impact fast-uri v3.1.1 and earlier decodes percent-encoded authority delimiters %40 as @, %3A as : inside the host component and serializes them back as raw characters. This changes the URI structure, turning a hostname into userinfo plus a different host. For example,...

NPM: fast-uri vulnerable to path traversal via percent-encoded dot segments

NPM: fast-uri vulnerable to path traversal via percent-encoded dot segments vulnerability discovered by ? in WordPress Npm fast-uri versions = 3.1.0...

SUSE CVE-2026-6321

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications...

Directory Traversal

Overview org.webjars.npm:nitropack is a Build and Deploy Universal JavaScript Servers Affected versions of this package are vulnerable to Directory Traversal via the routeRules function. An attacker can access files or endpoints outside the intended proxy scope by sending specially crafted URLs...

GHSA-5W89-W975-HF9Q Nitro has a proxy scope bypass via percent-encoded path traversal in `routeRules`

A proxy route rule like: ts routeRules: "/api/orders/": proxy: to: "http://upstream/orders/" is intended to limit the proxy to URLs under /api/orders/. Before the patch, an attacker could bypass that scope by sending percent-encoded path traversal ..%2f in the URL, causing Nitro to forward a...

CVE-2026-6321

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator URL containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization via improper handling of resource path matching and authorization checks. An attacker can gain unauthorized access to protected resources or perform unauthorized actions by crafting requests that exploit...

GHSA-RFGQ-WGG8-662P S3-Proxy has Security Issues in its Resource Path Matching Implementation

Background The original concern is functional: a resource pattern should treat a percent-encoded segment like some%2Fvalue as a single opaque token rather than splitting it into two path segments at the decoded /. Investigation into why %2F was being decoded and how routes matched against the...

Interpretation Conflict

Overview org.webjars.npm:fast-uri is a Dependency-free RFC 3986 URI toolbox Affected versions of this package are vulnerable to Interpretation Conflict during the decoding of URL host component. An attacker can manipulate the authority component of a URI by supplying percent-encoded delimiters,...

UBUNTU-CVE-2026-6322

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...

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...

PT-2026-36996

Name of the Vulnerable Software and Affected Versions fast-uri versions prior to 3.1.2 Description The normalize function decoded percent-encoded authority delimiters within the host component and re-emitted them as raw delimiters during serialization. This allows a host combining an allowed...

PT-2026-37288

Name of the Vulnerable Software and Affected Versions s3-proxy versions prior to 0.0.0-20260424211602-1320e4abd46a Description Inconsistent URL path normalization and routing logic lead to authorization bypasses, allowing unauthenticated access to protected objects. The issues stem from a mismatc...
