EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.0 under NVD CVSS v3. EPSS exploit probability: 2.7%, top 16% 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).

In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was found in retrieval of the current username (in libraries/classes/Server/Privileges.php and libraries/classes/UserPassword.php). A malicious user with access to the server could create a crafted username, and then trick the victim into performing specific actions with that user account (such as editing its privileges).
