SCA: security update for robrichards/xmlseclibs (GHSA-c4cc-x928-vjw9)

high Tenable Self-Hosted Container Security Plugin ID 436293

Description

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

 - xmlseclibs is a library written in PHP for working with XML Encryption and Signatures. Versions 3.1.3
 contain an authentication bypass vulnerability due to a flaw in the libxml2 canonicalization process
 during document transformation. When libxml2’s canonicalization is invoked on an invalid XML input, it may
 return an empty string rather than a canonicalized node. xmlseclibs then proceeds to compute the
 DigestValue over this empty string, treating it as if canonicalization succeeded. This issue is fixed in
 version 3.1.4. Workarounds include treating canonicalization failures (exceptions or nil/empty outputs) as
 fatal and aborting validation, and/or adding explicit checks to reject when canonicalize returns nil/empty
 or raises errors. (CVE-2025-66578)
