Daniel P. Berrange reports:
In the OpenStack Liberty release, the Glance project added support for image signature verification.
http://specs.openstack.org/openstack/glance-specs/specs/liberty/image-signing-and-verification-support.html
The verification code was added in the following git commit
https://github.com/openstack/glance/commit/484ef1b40b738c87adb203bba6107ddb4b04ff6e
Unfortunately the design of this signature verification method is flawed by design.
The generalized approach to creating signatures of content is to apply a hash to the content and then encrypt it in some manner. Consider that the signature is defined to use hash=sha256 and cipher=rsa we can describe the signature computation as

## CVE-2026-34881 :
OpenStack Glance vulnerability analysis and mitigation
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.
