h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

CVE-2026-80515

In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 the management-authorization gate that protects every /…/mgmt/… REST endpoint decides whether to apply its check by calling request.getRequestURL.toString.contains"/mgmt/". Tomcat returns getRequestURL un-decoded, while Spring MVC's...

CVE-2026-80515

Eclipse Arrowhead versions 5.0.0 through 5.2.1 are affected by an authorization-bypass vulnerability in the management REST endpoints. The root cause is a mismatch between Tomcat's undecoded getRequestURL() and Spring MVC's decoded routing: the management-authorization gate checks for the literal...

GHSA-JQFF-G426-HQXP fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

fast-uri: fast-uri: Server-Side Request Forgery via repeated hostname percent-decoding

A flaw was found in fast-uri, a URI parser for Node.js. The component incorrectly decodes percent escapes in a hostname twice during URI parsing and authority recomposition. This double decoding can allow a remote attacker to manipulate a URI to point to a different network destination, such as a...

fast-uri: fast-uri: URI parsing flaw enables server-side request forgery and redirects

A flaw was found in fast-uri, a software component used for parsing Uniform Resource Identifiers URIs in Node.js applications. This vulnerability arises from an issue in how fast-uri processes the scheme part of a URI, specifically when it contains special characters that are percent-encoded. An...

fast-uri: fast-uri: URI authority bypass due to improper delimiter handling

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier URI that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw...

Linux Distros Unpatched Vulnerability : CVE-2026-75899

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 decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authorit...

CVE-2026-76842

CVE-2026-76842 affects the Mercado Pago Node.js SDK (through 3.4.0 ). The payment, paymentRefund, advancedPayment, and disbursementRefund clients interpolate caller-supplied identifiers into API request paths via template literals without percent-encoding , so URL-structural characters (dot-dot, ...

CVE-2026-75899

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...

Name of the Vulnerable Software and Affected Versions fast-uri versions 2.4.1 through 2.4.4 fast-uri versions 3.1.2 through 3.1.5 fast-uri versions 4.0.0 through 4.1.2 Description This URI parser for Node.js decodes percent escapes in a hostname during parsing and subsequently decodes the parsed...

Mailpit: WebSocket origin check bypass via percent-encoded path (regression of CVE-2026-22689)

Summary The cross-site WebSocket hijacking fix was reimplemented as an origin check gated on a raw-URI prefix test, but Go's ServeMux routes on the percent-decoded path, so requesting /%61pi/events reaches the WebSocket handler while skipping the only origin control, and the upgrader itself accep...

Mailpit is an email testing tool and API for developers. From 1.29.0 until 1.30.6, Mailpit's server/server.go origin middleware checks the raw RequestURI for the /api/ prefix while Go's ServeMux routes using the percent-decoded URL path, and server/websockets/client.go configures...

CVE-2026-19670

Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...
