Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Cloud Skipper (org.springframework.cloud:spring-cloud-skipper) versions before 2.11.4 are vulnerable to remote code execution. An attacker with access to the Skipper server API can send a crafted upload request to write an arbitrary file to any location on the file system, which could lead to compromise of the server. Upgrade to version 2.11.4 or later.
