AI Analysis
Technical Summary
CVE-2026-51772 describes an SSRF vulnerability in OpenStack Glance's Image API (v2). When the show_multiple_locations option is enabled in glance-api.conf, an authenticated attacker can exploit this flaw by sending a specially crafted HTTP PATCH request to manipulate the locations attribute of an image that is in the queued state. This manipulation can lead to unauthorized server-side requests, potentially exposing sensitive information or allowing further attacks. The vulnerability is classified under CWE-918 (Server-Side Request Forgery).
Potential Impact
Successful exploitation allows an authenticated attacker to cause the server to make unintended HTTP requests, potentially leading to unauthorized access to internal resources or sensitive data. The CVSS score of 8.1 reflects high confidentiality and integrity impact, with no availability impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, consider disabling the show_multiple_locations configuration option in glance-api.conf if it is not required. Monitor official OpenStack security advisories for updates and apply any official fixes once released.
