Description OSIDB Bzimport 2026-03-30 12:08:44 UTC 
KeyPairsController#show bypasses taxonomy scoping, allowing authenticated users with view_keypairs permission to download private SSH keys across organizations by directly querying key pair IDs. This results in cross-tenant data exposure in multi-tenant deployments.

Requirements to exploit:

Authenticated user account
Permission view_keypairs (e.g., via Viewer role)
Ability to guess or enumerate KeyPair IDs (low complexity due to predictable IDs)
