How to Fix CVE-2026-34164

To remediate this vulnerability, upgrade all affected Valtimo dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.ritense.valtimo:inbox fixed: 13.22.0.RELEASE 
<dependency>
    <groupId>com.ritense.valtimo</groupId>
    <artifactId>inbox</artifactId>
    <version>13.22.0.RELEASE</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.ritense.valtimo

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-34164, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.ritense.valtimo

Analyze the terminal output to locate any version of Valtimo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.22.0.RELEASE), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.ritense.valtimo command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Valtimo, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary The `InboxHandlingService` logs the full content of every incoming inbox message at INFO level (`logger.info("Received message: {}", message)`). Inbox messages are wrappers around outbox message data, which can contain highly sensitive information such as personal data (PII), citizen identifiers (BSN), and case details. ### Impact This data is exposed to: - Anyone with access to application logs (stdout/log files) - Any Valtimo user with the admin role, through the logging module in the Admin UI ### Affected Code `com.ritense.inbox.InboxHandlingService#handle` in the `inbox` module. ### Resolution Fixed in [13.22.0](https://github.com/valtimo-platform/valtimo/releases/tag/13.22.0) via commit [`f16a1940ba`](https://github.com/valtimo-platform/valtimo/commit/f16a1940ba7b34627c0b966f98ca78655ace9335) (PR [#497](https://github.com/valtimo-platform/valtimo/pull/497), tracking issue [gzac-issues#653](https://github.com/generiekzaakafhandelcomponent/gzac-issues/issues/653)). The log statement was downgraded from INFO to DEBUG and the message payload was removed from the log output. ### Mitigation For versions before 13.22.0, consider: - Restricting access to application logs - Adjusting the log level for `com.ritense.inbox` to WARN or higher in your application configuration
