TL;DR: SAP GUI input history is stored weakly encrypted on Windows and unencrypted on Java clients, creating local data exposure that can surface usernames, identifiers, and other sensitive fields; SAP issued patches and mitigations in January 2025, according to Pathlock research. The real issue is not just encryption strength but the governance assumption that client-side history is safe enough to retain.
Editorial analysis by NHI Mgmt Group, based on content published by Pathlock: “Responsible Disclosure: Vulnerabilities in SAP GUI Client (CVE-2025-0056 & CVE-2025-0055)”.
Key questions
Q: What should teams do when a client application stores sensitive history on local devices?
A: Treat the feature as a data-retention control, not a convenience setting.
Q: Why does weak client-side history storage create an IAM risk?
A: Because the retained values often reveal who uses which systems, what data they handle, and which business workflows they touch.
Q: What are the signs that GUI input history controls are failing?
A: Look for local files that persist across logins, evidence that sensitive fields appear in user history, and inconsistent behavior between client variants.
Practitioner guidance
- Disable client-side input history where it captures sensitive fields Turn off SAP GUI history for Windows and Java wherever business processes can tolerate it, and do not rely on patching alone when local retention is the exposure mechanism.
- Remove existing history files from affected endpoints Delete cached .db files and serialized history objects from the documented local storage paths after disabling the feature so older values do not remain recoverable.
- Review endpoint storage for identity and finance data Inventory whether local workstation caches contain usernames, national IDs, bank details, internal table names, or similar high-value fields that should never be retained in user history.
Bottom line: Client-side input history can become a hidden sensitive-data store when applications retain usernames, identifiers, and other entered values on local devices.

Client-side history retention is a data governance decision, not a UI convenience: When an application stores prior inputs locally, it creates a second data estate outside the core application control plane. That estate must be governed as sensitive data because it can include identity and financial fields that users never intended to persist. The practitioner takeaway is to decide whether the history feature should exist at all, rather than assuming retention is harmless.
A question worth separating out:
Q: Should organisations disable client history or rely on patching it?
A: If the history can contain sensitive data, disabling it is usually the safer governance choice. Patching reduces exposure in a specific release, but it does not remove the underlying design assumption that locally retained history is acceptable. When that assumption is wrong, the feature itself remains the risk.
