OSSA-2026-047: Redfish vendor_passthru method allows path injection via ID

Date:

October 22, 2026

CVE:

CVE-2026-90458

Affects

• Ironic: >=18.1.0 <=29.1.1, >30.0.0 <=32.1.1, >33.0.0 <=35.1.1, >36.0.0 <=39.0.1

Description

The Metal3.io Security team reported a vulnerability in Ironic’s API. When calling the vendor_passthru API endpoint provided by the redfish management interface to create or delete a subscription, a malicious System-scoped Administrator could instead perform an HTTP DELETE or HTTP GET on an arbitrary path on a node’s BMC. In a worst case scenario, this could lead to user accounts being deleted from the Redfish service on the BMC.

Only clouds with nodes enrolled in a redfish hardware type are susceptible to this vulnerability.
