Echo: multer: security update to 2.3.0

low Tenable Cloud Security Plugin ID 460294

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. When an application uses an
asynchronous fileFilter together with the fileSize limit, a race condition in multer's file stream
handling can allow a file that exceeds the configured size limit to bypass the size-limit rejection. All
versions before 2.3.0 are affected. The impact is limited because the underlying multipart parser still
truncates the stream at the size limit, so this is a bypass of the limit rejection rather than
uncontrolled resource consumption. The issue is fixed in multer 2.3.0. Upgrade to multer 2.3.0 to
remediate. (CVE-2026-77063)

Solution

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