high Tenable Cloud Security Plugin ID 439440

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 tempo/session
 cooperative close handler validated the close voucher amount using "<" instead of "<=" against the on-
 chain settled amount. An attacker could submit a close voucher exactly equal to the settled amount, which
 would be accepted without committing any new funds, effectively closing or griefing the channel for free.
 This issue has been patched in version 0.4.11. (CVE-2026-34209)

Solution

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