SCA: security update for multer (GHSA-72gw-mp4g-v24j)

high Tenable Self-Hosted Container Security Plugin ID 443368

Description

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

- Impact: multer versions 1.0.0 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service via
deeply nested field names in multipart form data. The append-field dependency parses bracket notation in
field names with no limit on nesting depth, allowing an attacker to force allocation of deeply nested
object structures that consume CPU and memory. A single HTTP request with a crafted multipart body is
sufficient to exploit this. Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x
prerelease) and configure the new limits.fieldNestingDepth option to the minimum depth their application
requires. Workarounds: Set limits.fields to a reasonable value to reduce the number of fields an attacker
can send per request. This does not fully mitigate the issue but limits the impact. (CVE-2026-5079)

Solution

Update the multer library and its related packages to version 2.2.0 or later.
