CVE-2023-34205: Signature validation bypass in github.com/moov-io/signedxml

May 30, 2023 (updated January 13, 2025)

In Moov signedxml through 1.0.0, parsing the raw XML (as received) can result in different output than parsing the canonicalized XML. Thus, signature validation can be bypassed via a Signature Wrapping attack (aka XSW).
