EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.9 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 76% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Gibbon versions before v30.0.01 are affected by a local file inclusion vulnerability resulting in RCE by changing the report archive directory and forcing interpretation of a user provided .zip as PHP. Successful exploitation requires Teacher or higher privileges. Exploitation could result in compromise of the underlying web server.
