SCA: security update for mppx (GHSA-8mhj-rffc-rcvw)

medium Tenable Self-Hosted Container Security Plugin ID 439429

Description

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

 - mppx is a TypeScript interface for machine payments protocol. Prior to version 0.4.11, the stripe/charge
 payment method did not check Stripe's Idempotent-Replayed response header when creating PaymentIntents. An
 attacker could replay a valid credential containing the same spt token against a new challenge, and the
 server would accept the replayed Stripe PaymentIntent as a new successful payment without actually
 charging the customer again. This allowed an attacker to pay once and consume unlimited resources by
 replaying the credential. This issue has been patched in version 0.4.11. (CVE-2026-34210)

Solution

Update the mppx library and its related packages to version 0.4.11 or later.
