EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 2.4%, top 18% 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 TripleO Heat templates (tripleo-heat-templates) do not properly order the Identity Service (keystone) before the OpenStack Object Storage (Swift) staticweb middleware in the swiftproxy pipeline when the staticweb middleware is enabled, which might allow remote attackers to obtain sensitive information from private containers via unspecified vectors.
