SCA: security update for multiparty (GHSA-65x3-rw7q-gx94)

high Tenable Cloud Security Plugin ID 442056

Description

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

 - [email protected] and lower versions are vulnerable to denial of service via regular expression
 backtracking in the Content-Disposition filename parameter parser. A crafted multipart upload with a long
 header value can cause regex matching to take seconds, blocking the event loop. Impact: any service
 accepting multipart uploads via multiparty is affected. Workarounds: limiting upload sizes at the proxy or
 gateway layer reduces but does not eliminate the attack surface, since a small header of around 8 KB is
 sufficient to trigger the vulnerable backtracking. Upgrade to [email protected] or higher. (CVE-2026-8159)

Solution

Update the multiparty library and its related packages to version 4.3.0 or later.
