SCA: security update for github.com/moov-io/signedxml (GHSA-5588-rp99-5fjh)

high Tenable Cloud Security Plugin ID 476567

Description

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

 - Moov signedxml is a pure Go library for processing signed XML documents. Prior to 1.4.1,
 ExclusiveCanonicalization in exclusivecanonicalization.go copies the complete accumulated namespace map at
 every nested element before reference digest or signature checks. Attacker-controlled XML containing
 deeply nested elements with many unused namespace declarations causes quadratic allocation growth with
 depth and linear growth with prefixes per level, allowing a comparatively small document to consume
 multiple gigabytes of memory and terminate the process. The condition is reachable through
 ValidateReferences without a valid signature, matching certificate, or prior authentication, and it does
 not bypass signature verification. This issue is fixed in version 1.4.1. (CVE-2026-113729)

Solution

Update the github.com/moov-io/signedxml library and its related packages to version 1.4.1 or later.
