## Technical details

An SSRF vulnerability in OpenStack Glance's Image API v2 allows an authenticated attacker to manipulate the locations attribute of an image in queued state via a crafted HTTP PATCH request when show_multiple_locations is enabled in glance-api.conf. This enables the attacker to forge requests from the Glance server to arbitrary network endpoints, potentially leading to access of internal services or data exposure.
