EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.1 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 81% 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).

Vvveb before version 1.0.8.2 contains an XML external entity (XXE) injection vulnerability in the admin Tools/Import feature that allows authenticated site_admin users to read arbitrary files and modify database records. Attackers can exploit the XML parser configuration in system/import/xml.php to inject file:// or php://filter entity references that are resolved and persisted into the application database, enabling arbitrary file disclosure and administrator password hash overwriting for privilege escalation.
