Echo: multer: security update to 2.3.0

high Tenable Self-Hosted Container Security Plugin ID 464069

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. In version 2.2.0, when a disk-backed
 upload is aborted or truncated before the write stream finishes, multer's disk storage engine removes the
 visible file but does not close the underlying write file descriptor, leaving a deleted but still open
 descriptor. A remote attacker able to reach an upload route using the built-in disk storage can send
 repeated aborted or malformed multipart uploads, each one leaking a file descriptor and retaining disk
 blocks until the process exits, which can exhaust resources and cause a denial of service. The issue is
 fixed in multer 2.3.0, which closes the destination write stream on abnormal source termination and defers
 cleanup until the stream has closed. Upgrade to multer 2.3.0 to remediate. (CVE-2026-77037)

Solution

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