EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 1.3%, top 20% 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).

A fix is available — apply it.

The installation script in Katello 1.0 and earlier does not properly generate the Application.config.secret_token value, which causes each default installation to have the same secret token, and allows remote attackers to authenticate to the CloudForms System Engine web interface as an arbitrary user by creating a cookie using the default secret_token.
