Machine-written summary

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

OpenStack Swift versions before 2.37.2 are affected. An authenticated user with write access can inject internal update headers so that proxy-server forwards container update requests to an attacker-controlled server, enabling server-side request forgery that can expose internal cluster metadata and, with at-rest encryption enabled, encryption material. Upgrade to swift 2.37.2 or later.
