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...

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...

EUVD-2026-63668

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 Incorrect Authorization in CISA Malcolm

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...

CVE-2026-19670

Malcolm's nginx Lua RBAC layer pattern-matches the raw percent-encoded URI while nginx routes using the decoded URI, allowing an authenticated low-privilege user to access admin-only paths via encoded URLs like /%68tadmin.php. CVSS 5.4 (MEDIUM); no in-the-wild exploitation reported. No patch vers...

CVE-2026-73851 Kiota: Path traversal in generated plugin manifest static_template.file reference (percent-encoding bypass)

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.34.0, an attacker who controls or tampers with the OpenAPI description consumed by Kiota can supply a file reference that resolves outside the manifest package e.g. ../../../../etc/passwd, an absolute path, or a file:// /...
