CVE-2026-66027Public exploitNetwork attack vector

Cross-tenant queue manipulation via missing ownership checks

Published Jul 24, 2026 · Updated Jul 24, 2026

Broken access control in Kortix Suna before 0.9.102 allows remote authenticated users to manipulate other tenants' message queues. The /v1/queue handlers use a caller-supplied session ID to read, enqueue, or clear filesystem-backed queues without consulting the authenticated user ID or session ownership. Any registered account can expose or delete pending prompts and inject instructions that the drainer forwards to another tenant's running agent under that tenant's credentials and permissions.
