CVE-Mapping between Trivy Analyzer and NVD

[SpiritCrusherKern]

I am currently working with DependencyTrack v4.13.2 and a Trivy Analyzer Instance with the latest Version (0.67.2).
The issue is fully reproducable with the information below.

By the end of October a CVE-2025-55754 was published (https://nvd.nist.gov/vuln/detail/CVE-2025-55754) which is currently 'awaiting analysis', in particular CVSSv3.x shows Base Score 'N/A' (NVD) but also '9.6 CRITICAL' (CISA-ADP).

I scanned my container image and by 'trivy image ' I get the Severity 'LOW' by its source https://avd.aquasec.com/nvd/cve-2025-55754. This is also what I expect to get, when the Trivy Analyzer I set up with Dependency-Track analyzes component 'tomcat-embed-core v9.0.105'.
On the other hand: Mirroring CVEs from NVD gets me (shortened for more readability):
"cve": { "id": "CVE-2025-55754", "sourceIdentifier": "[email protected]", "published": "2025-10-27T18:15:42.710", "lastModified": "2025-11-04T22:16:31.360", "vulnStatus": "Awaiting Analysis", "cveTags": [], "descriptions": [...], "metrics": { "cvssMetricV31": [ { "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H", "baseScore": 9.6, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH" }, "exploitabilityScore": 2.8, "impactScore": 6 } ] }, ... }
in particular it has Severity Critical (reproducible via curl https://services.nvd.nist.gov/rest/json/cves/2.0?cveid=CVE-2025-55754).

If both is available (i.e. the above CVE is mirrored to Dependency-Track and Trivy Analyzer is working properly), then the severity 'critical' takes precedence over 'low'.
On the other hand: If only the knowledge of trivy analyzer is available (i.e. severity 'low'), then this knowledge is stored into the vulnerability database of Dependency-Track.

Why is that? How does the Mapping between Trivy Findings and NVD work within Dependency-Track? What is the correct way to read this (although I think the answer depends on policies).
