Technical Analysis
CVE-2026-71201 describes an information disclosure vulnerability in OpenStack Ironic up to version 38.0.0. A user with project reader privileges can send a specially crafted request to the Ironic service and obtain Portgroup information associated with Nodes belonging to other projects. This cross-project data leakage could expose network configuration details that should otherwise be restricted. The vulnerability does not allow modification or denial of service, only read access to restricted data.
Potential Impact
The vulnerability allows unauthorized users with project reader roles to access Portgroup information assigned to Nodes owned or leased by other projects. This leads to information disclosure of network configuration details, which could aid an attacker in further reconnaissance or planning attacks. There is no impact on data integrity or service availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict project reader privileges to trusted users only and monitor access patterns for suspicious activity related to Portgroup queries.
