CVE-2026-51772

openstack-glance: openstack-glance: Server-Side Request Forgery via image locations manipulation

A Server-Side Request Forgery (SSRF) vulnerability exists in the Image API (v2) of OpenStack Glance. When the show_multiple_locations configuration option is enabled in glance-api.conf, an authenticated attacker can manipulate the locations attribute of an image in the queued state by sending a crafted HTTP PATCH request

Openstack glance: swift: s3: openstack glance: information disclosure of backend credentials via cached image request

A flaw was found in OpenStack Glance. Remote authenticated users can exploit this vulnerability by requesting a cached image when the single-tenant Swift or S3 store is in use. This action causes the system to report the location field, which can lead to the disclosure of the operator's backend credentials.

glance-store: glance_store: glance_store: Information disclosure via unvalidated external image location URI

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.

openstack-glance: API v1 copy_from reveals network details

An SSRF issue was discovered in OpenStack Glance before Newton. The 'copy_from' feature in the Image Service API v1 allowed an attacker to perform masked network port scans. With v1, it is possible to create images with a URL such as 'http://localhost:22'. This could then allow an attacker to enumerate internal network details while appearing masked, since the scan would appear to originate from the Glance Image service.

CVE-2026-71198

openstack-glance: openstack-glance: SSRF via location API missing host validation

In OpenStack Glance before 32.0.1, the location API does not validate destination hosts when adding an HTTP location to an image. Unlike the web-download import path, the location API only checks the URL scheme and does not apply the import_filtering_opts host restrictions. An authenticated user can add a location pointing to internal endpoints such as the cloud metadata service (169.254.169.254), and retrieve the response by downloading the image data. This affects both the new POST /v2/images/{id}/locations API and the old PATCH API when show_multiple_locations is enabled. Deployments with the HTTP store backend enabled are affected.

CVE-2026-71196

openstack-glance: openstack-glance: SSRF via web-download import due to empty default host filters

A server-side request forgery (SSRF) vulnerability was found in OpenStack Glance. The web-download image import method allows authenticated users to provide a URI from which the Glance service fetches data. Due to insufficient default host filtering, an attacker with standard tenant credentials can make Glance issue HTTP requests to arbitrary internal network hosts, including the cloud metadata service. The fetched response is stored as image data and can be downloaded by the attacker, enabling exfiltration of sensitive internal data such as cloud instance credentials.

openstack-glance: openstack-glance: SSRF blocklist bypass via hostname-to-IP resolution gap in web-download

A flaw was found in OpenStack Glance. The web-download image import method can bypass host-based blocklist filtering. When an operator configures disallowed_hosts with IP addresses to block access to internal services, an attacker can circumvent this protection by using a hostname that resolves to the blocked IP address. The hostname-to-IP resolution result is not used for blocklist comparison, allowing an authenticated user to force the Glance server to make requests to internal network services that were intended to be blocked.

glance: OpenStack Glance: Server-Side Request Forgery allows internal URL access by administrators

In OpenStack Glance through 32.0.0, the /v2/tasks API accepts type=import tasks that bypass import_filtering_opts, allowing an admin to fetch internal URLs from the Glance service network (aka SSRF), as long as https:// or http:// is used. This API has been available only to admins since Xena, and it has been deprecated for several releases.

OpenStack Glance: OpenStack Glance: Server-Side Request Forgery via HTTP redirects in image import

OpenStack Glance before 29.1.1, 30.x before 30.1.1, and 31.0.0 is affected by Server-Side Request Forgery (SSRF). By use of HTTP redirects, an authenticated user can bypass URL validation checks and redirect to internal services. Only glance image import functionality is affected. In particular, the web-download and glance-download import methods are subject to this vulnerability, as is the optional (not enabled by default) ovf_process image import plugin.

OpenStack: malicious qcow2/vmdk images

An issue was discovered in OpenStack Cinder through 24.0.0, Glance before 28.0.2, and Nova before 29.0.3. Arbitrary file access can occur via custom QCOW2 external data. By supplying a crafted QCOW2 image that references a specific data file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Cinder and Nova deployments are affected; only Glance deployments with image conversion enabled are affected.
