Package : python-keystonemiddleware CVE ID : CVE-2026-22797

Grzegorz Grasza discovered a vulnerability in the Openstack middleware to provide authentication and authorization features to web services other than Keystone: If an external OAuth provider is configured, authentication headers are insufficiently sanitised, which could result in privilege escalation or user impersonation.

The oldstable distribution (bookworm) is not affected.

For the stable distribution (trixie), this problem has been fixed in version 10.9.0-2+deb13u1.

We recommend that you upgrade your python-keystonemiddleware packages.
