EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.8 under NVD CVSS v3. EPSS exploit probability: 0.8%, top 48% 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 checkHTTP function in libraries/Config.class.php in phpMyAdmin 4.5.x before 4.5.5.1 does not verify X.509 certificates from api.github.com SSL servers, which allows man-in-the-middle attackers to spoof these servers and obtain sensitive information via a crafted certificate.
