Local test-data disclosure via unsafe temporary permissions
Published Jan 31, 2024 · Updated Jun 3, 2025
Information disclosure in Spring Cloud Contract 3.1.0 through 3.1.9, 4.0.0 through 4.0.4, and 4.1.0 allows local users to read test data. The shaded Guava dependency uses com.google.common.io.Files.createTempDir(), which creates a shared temporary directory with permissions that let other users traverse and read its files. Exploitation requires a co-resident low-privileged user on a Unix-like test host while sensitive data remains in the generated directory.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=3.1.0 <3.1.10
- Affected versionversion=4.0.0 <4.0.6
- Affected versionversion=4.1.0 <4.1.1
