CVE-2023-51699

Container command execution via unescaped runtime fields

Published Mar 15, 2024 · Updated Aug 2, 2024

OS command injection in Fluid before 0.9.3 allows remote authenticated users to execute commands in JuiceFS-related containers. JuiceFSEngine command generation concatenates Dataset mount names, mount paths, storage settings, and options into shell command strings without escaping metacharacters. Exploitation requires permission to create or update Dataset and JuiceFSRuntime resources and exposes container-accessible data to reading, modification, or deletion.
