Authenticated file disclosure via native repository path traversal

Published Aug 27, 2026 · Updated Aug 27, 2026

Path traversal in Spring Cloud Config Server allows remote authenticated users to read files outside the configured native repository. NativeEnvironmentRepository fails to keep resolved configuration-file locations beneath the configured search locations. Exploitation requires high privileges and the native filesystem backend; the published impact is file disclosure only, without integrity or availability loss.
