Valtimo is affected by a sensitive information exposure vulnerability, where confidential data may be written to application logs, risking unauthorized access by administrative users.

This is a CWE-532 vulnerability involving the insertion of sensitive information into log files. The vulnerability requires high privileges (PR:H) to exploit, as an attacker must typically access the server or log management systems to retrieve the exposed data.

Successful exploitation results in the exposure of sensitive business or user data contained within log files. This could lead to a breach of confidentiality and regulatory non-compliance. The CVSS score of 7.6 highlights the critical nature of this disclosure, particularly in enterprise environments where business processes are automated.

Immediate Action: Update the Valtimo platform to version 12.33.0 or 13.26.0 depending on the current deployment branch.

Proactive Monitoring: Review existing log files for the presence of sensitive data and rotate logs that may contain exposed information.

Compensating Controls: Restrict access to log management systems (e.g., ELK, Splunk) to only essential administrative personnel to limit the exposure window.

Public Exploit Available: No

Administrators should prioritize patching the Valtimo platform to the specified versions to prevent sensitive data leakage. Furthermore, auditing existing logs for historical exposure is recommended to ensure that no sensitive data has already been compromised by unauthorized personnel.
