Sensitive data exposure through undisclosed logging
Published Aug 27, 2026 · Updated Aug 27, 2026
Sensitive-data logging in Spring Cloud Stream 4.2.0 through 4.2.6, 4.3.0 through 4.3.3, and 5.0.0 through 5.0.2 allows attackers to expose data. Spring has not published the affected logging component, the data involved, or the operation that places it in logs. Exploitation requires network access, high privileges, and user interaction, but the vendor has not identified which data can enter logs or how.

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=4.2.0 <=4.2.6
- Affected versionversion=4.3.0 <=4.3.3
- Affected versionversion=5.0.0 <=5.0.2
