Echo: multer: security update to 2.3.0

high Tenable Cloud Security Plugin ID 465433

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - multer is a middleware for handling multipart/form-data in Node.js. A small multipart request containing
 two specially crafted text field names can cause an uncaught RangeError (Invalid array length) that
 terminates the Node.js process. The first field uses a very large numeric array index to allocate a
 maximum-length sparse array, and a second field then pushes past that length, which throws inside the
 append-field dependency and is not caught by multer. All versions before 2.3.0 are affected, and the issue
 is a remotely triggerable denial of service. The issue is fixed in multer 2.3.0. Upgrade to multer 2.3.0
 to remediate. (CVE-2026-77078)

Solution

Update the multer library and its related packages to version 2.3.0 or later.
