CVE-2026-80183: In OpenStack Keystone before 29.0.3, any authenticated user holding role:reader on any project can list every project-scoped role assignment

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.38% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenStack Keystone 27.0.3, 28.0.3, 29.0.3.

Low priority for now. Upgrade to OpenStack Keystone 27.0.3, 28.0.3, 29.0.3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
