description

Yosemite-Crew main and development snapshots expose service and PMS task-library/template operations without consistent organization or permission enforcement. A registered user may alter or remove another organization's records, while service records may be readable without authentication; exposure requires access to the affected deployment and, for modification, a registered account.

mitigation

Restrict or disable the affected routes until organization-scoped authorization and role checks are enforced for every service and PMS task-library/template operation. Require authentication for service reads and constrain data access by organization; no fixed release is recorded.
