Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

OpenStack Keystone versions 13.0.0 through 29.0.1 are affected. An attacker holding an unrestricted application credential for one project can create an EC2-type credential for a different project, because the request is not checked against the project of the authenticating credential. The attacker can then obtain a token scoped to the other project and move across projects within the original credential owner's roles. The source lists no fixed version and no workaround.
