Published Apr 16, 2026 · Updated Apr 16, 2026

Sensitive data logging in Ritense Valtimo 13.0.0 through 13.21.0 allows remote authenticated users to read inbox message contents. The InboxHandlingService.handle method writes the complete untrusted message string to an INFO log entry, exposing PII, citizen identifiers, and case details. Access requires the admin role through the logging UI or separate access to application logs; the reported impact is disclosure only.
