CVE-2026-86253

h3 (npm package) versions up to 2.0.1-rc.14 and 1.x before 1.15.6 are affected by a path traversal vulnerability in serveStatic() . On Node.js deployments, the URL pathname is not normalized before being passed to decodeURI(), so percent-encoded dot segments (%2e%2e) decode to ../ sequences witho...

Security Advisory: Remote Denial of Service via Reachable Assertion in URL Prefix Handling rouille Assigned CVE ID: CVE-2026-66754 Summary Request::removeprefix tests the percent-decoded URL but asserts on the raw one. A request whose decoded path starts with the prefix while its raw path does no...

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...

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...

GHSA-8R62-W5WH-FC5M 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...
