CVE-2023-34205

9.1 criticalEPSS 0.4%

Critical (9.1) in moov signedxml. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/moov-io/signedxml 1.1.0.

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).
