{"id":"GHSA-hfrg-mcvw-8mch","summary":"Valtimo: Sensitive data exposure through inbox message logging in InboxHandlingService","details":"### Summary\n\nThe `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.\n\n### Impact\n\nThis data is exposed to:\n- Anyone with access to application logs (stdout/log files)\n- Any Valtimo user with the admin role, through the logging module in the Admin UI\n\n### Affected Code\n\n`com.ritense.inbox.InboxHandlingService#handle` in the `inbox` module.\n\n### Resolution\n\nFixed 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.\n\n### Mitigation\n\nFor versions before 13.22.0, consider:\n- Restricting access to application logs\n- Adjusting the log level for `com.ritense.inbox` to WARN or higher in your application configuration","aliases":["CVE-2026-34164"],"modified":"2026-09-10T03:51:01.978647389Z","published":"2026-04-16T20:42:55Z","database_specific":{"cwe_ids":["CWE-532"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-16T20:42:55Z","nvd_published_at":"2026-04-16T22:16:37Z"},"references":[{"type":"WEB","url":"https://github.com/valtimo-platform/valtimo/security/advisories/GHSA-hfrg-mcvw-8mch"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34164"},{"type":"WEB","url":"https://github.com/generiekzaakafhandelcomponent/gzac-issues/issues/653"},{"type":"WEB","url":"https://github.com/valtimo-platform/valtimo/pull/497"},{"type":"WEB","url":"https://github.com/valtimo-platform/valtimo/commit/f16a1940ba7b34627c0b966f98ca78655ace9335"},{"type":"PACKAGE","url":"https://github.com/valtimo-platform/valtimo"},{"type":"WEB","url":"https://github.com/valtimo-platform/valtimo/releases/tag/13.22.0"}],"affected":[{"package":{"name":"com.ritense.valtimo:inbox","ecosystem":"Maven","purl":"pkg:maven/com.ritense.valtimo/inbox"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0.RELEASE"},{"fixed":"13.22.0.RELEASE"}]}],"versions":["13.0.0.RELEASE","13.0.1.RELEASE","13.0.2.RELEASE","13.1.0.RELEASE","13.1.1.RELEASE","13.1.2.RELEASE","13.1.3.RELEASE","13.10.0.RELEASE","13.11.0.RELEASE","13.12.0.RELEASE","13.13.0.RELEASE","13.14.0.RELEASE","13.15.0.RELEASE","13.16.0.RELEASE","13.17.0.RELEASE","13.17.1.RELEASE","13.18.0.RELEASE","13.19.0.RELEASE","13.2.0.RELEASE","13.2.1.RELEASE","13.20.0.RELEASE","13.21.0.RELEASE","13.3.0.RELEASE","13.4.0.RELEASE","13.4.1.RELEASE","13.4.2.RELEASE","13.5.0.RELEASE","13.5.1.RELEASE","13.6.0.RELEASE","13.7.0.RELEASE","13.8.0.RELEASE","13.9.0.RELEASE","13.9.1.RELEASE"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-hfrg-mcvw-8mch/GHSA-hfrg-mcvw-8mch.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"}]}
