CVE-2026-67348Public exploitNetwork attack vector

Cross-tenant data disclosure via unscoped execution lookup

Published Jul 30, 2026 · Updated Jul 30, 2026

Authorization bypass in Julep allows remote authenticated users to read other tenants' execution data through the executions API. The get_execution_details handler passes only the attacker-controlled execution_id to a query whose WHERE clause omits developer_id, so the X-Developer-Id tenant context is never enforced. A shared API key and any tenant identity suffice in multi-tenant mode; exposed task tokens also permit interference with another tenant's paused execution.
