Doc Text:
A flaw was found in Spring Data Geode. A local user with basic privileges on a shared host can exploit an insecure directory used during snapshot import. This vulnerability allows the system to extract archives into predictable and permissive temporary directories, enabling the local user to access another user’s extracted snapshot contents. This leads to the unintended exposure of sensitive cache data.
