EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 87% 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.

In OpenStack Keystone before 29.0.3, any authenticated user holding role:reader on any project can list every project-scoped role assignment under any domain by passing a domain ID as scope.project.id with include_subtree to the GET /v3/role_assignments endpoint. The domain's project record has domain_id=null, causing the policy domain_id check to pass for any caller. With include_names, the response discloses the names and home-domain IDs of every user, group, project, and role involved. The literal "default" domain ID works against any deployment created with keystone-manage bootstrap. An attacker can harvest domain IDs from the response and repeat the query to map role assignments across the entire cloud. This is caused by misuse of "None" in 

list_role_assignments_for_tree.
