Summary
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.
Risk Assessment
An attacker can obtain backend credentials, potentially leading to further unauthorized actions in the cloud infrastructure. The risk affects OpenStack Glance environments with Swift or S3 storage.
Recommendation
Update OpenStack Glance to a version containing the fix. Restrict access to the location field for unprivileged users.
Other vulnerabilities in OpenStack Glance
See all- CVE-2026-51772Medium
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.
- CVE-2026-71198High
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.
- CVE-2026-77648Low
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 (SSRF).
- CVE-2026-34881Medium
OpenStack Glance before versions 29.1.1, 30.1.1, and 31.0.0 is vulnerable to Server-Side Request Forgery (SSRF). An authenticated user can bypass URL validation checks using HTTP redirects to access internal services. The vulnerability affects only the image import functionality, specifically the web-download and glance-download import methods, as well as the optional ovf_process plugin.
- CVE-2017-7200Medium
OpenStack Glance before Newton has an SSRF vulnerability in the 'copy_from' feature of the Image Service API v1. An attacker can create images with URLs like 'http://localhost:22' to perform masked internal port scans.
