AI Analysis
Technical Summary
Valtimo versions 13.0.0 to 13.21.0 have a CWE-532 vulnerability where the InboxHandlingService logs entire inbox message contents at INFO level. These messages may contain sensitive data including personal identifiers and case details. This logging behavior exposes sensitive information to users with access to logs or admin UI modules. The vulnerability is resolved in version 13.22.0. Workarounds include restricting log access and configuring the logging level for com.ritense.inbox to WARN or higher to prevent sensitive data from being logged at INFO level.
Potential Impact
Sensitive personal data such as PII, citizen identifiers (BSN), and case details are exposed in application logs accessible to users with log access or admin privileges. This exposure risks unauthorized disclosure of confidential information. The vulnerability does not affect system integrity or availability but compromises confidentiality.
Mitigation Recommendations
Upgrade to Valtimo version 13.22.0 or later, where the issue is fixed. If immediate upgrade is not possible, restrict access to application logs to trusted personnel only and configure the logging level for com.ritense.inbox to WARN or higher to prevent sensitive data from being logged at INFO level. These steps reduce the risk of sensitive data exposure via logs.
