EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 4.0%, top 11% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

The application plugins in Apache CXF Fediz 1.2.x before 1.2.3 and 1.3.x before 1.3.1 do not match SAML AudienceRestriction values against configured audience URIs, which might allow remote attackers to have bypass intended restrictions and have unspecified other impact via a crafted SAML token with a trusted signature.
