CVE-2023-34205: Moov Signedxml

Critical severity, CVSS 9.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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).

Affected products

• Moov Signedxml: version 1.0.0 only
