GHSA-hfrg-mcvw-8mch
MEDIUMGHSA-hfrg-mcvw-8mch is a medium-severity (CVSS 4.9) vulnerability in com.ritense.valtimo:inbox. O3 Security confirms whether GHSA-hfrg-mcvw-8mch is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Valtimo: Sensitive data exposure through inbox message logging in InboxHandlingService
Blast Radius
com.ritense.valtimo:inboxReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
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 via commit f16a1940ba (PR #497, tracking issue gzac-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.inboxto WARN or higher in your application configuration
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.ritense.valtimo:inbox. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update com.ritense.valtimo:inbox to 13.22.0.RELEASE or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hfrg-mcvw-8mch is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-hfrg-mcvw-8mch is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-hfrg-mcvw-8mch. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-hfrg-mcvw-8mch in your dependencies?
O3 detects GHSA-hfrg-mcvw-8mch across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
