CVE-2026-51773: n/a
An issue in the VMware datastore driver of OpenStack glance_store. When an authenticated attacker provides a maliciously crafted image location URI pointing to an external server, the _retry_request function fails to validate the destination host before attaching sensitive authentication headers.
AI Analysis
Technical Summary
This vulnerability exists in the VMware datastore driver component of OpenStack glance_store. When an authenticated user provides a crafted image location URI referencing an external server, the internal _retry_request function fails to verify the destination host. As a result, sensitive authentication headers are sent to the external server, which could lead to unauthorized disclosure of credentials or tokens.
Potential Impact
The impact is the potential exposure of sensitive authentication headers to an attacker-controlled external server. This could enable attackers to misuse these credentials for further unauthorized access or actions within the OpenStack environment. Exploitation requires authentication, limiting the attack surface to authenticated users.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user permissions to trusted users only and monitor for suspicious activity involving image location URIs referencing external servers.
