Description OSIDB Bzimport 2026-10-09 14:18:44 UTC
Ironic Redfish vendor_passthru get_subscription and delete_subscription concatenate operator-supplied subscription id into the BMC Redfish path without blocking traversal (ironic/drivers/modules/redfish/vendor.py). Sushy URL resolution can escape EventService/Subscriptions and issue GET or DELETE on other Redfish resources using the conductor BMC-admin session. Default policy baremetal:node:vendor_passthru is SYSTEM_ADMIN. Upstream: https://bugs.launchpad.net/ironic/+bug/2166507 CVE-2026-90458 unembargo 2026-10-22T15:00:00Z. PSIRTSUPT-25485.
