Prior to 5.2.0, by-id read endpoints in `src/main/kotlin/nl/info/zac/app/zaak/ZaakRestService.kt` omit `assertPolicy`(`policyService.readZaakRechten(zaak).lezen`) authorization. `RequestAuthorizationFilter` and `hasAnyApplicationRole` require only an application role on any zaaktype, not the target case's type, while `zaak-rechten.rego` enforces the actual `zaaktype_allowed` boundary only when invoked. An authenticated low-privileged municipal user who knows a case or decision UUID can use `GET /rest/zaken/besluit/zaakUuid/{uuid}` (`listBesluitenForZaakUUID`) to read decisions including types, dates, and free-text toelichting; `GET /rest/zaken/besluit/{uuid}/historie` (`listBesluitHistorie`) to read audit old/new values; and `GET /rest/zaken/{uuid}/process-diagram` (`downloadProcessDiagram`) to read BPMN workflow state across unauthorized zaaktypes. The advisory also identifies `zaak/{uuid}/afzender` (`listAfzendersVoorZaak`) as exposing zaaktype mailbox configuration without a policy check. The search/_zoek path is correctly authorization-filtered and is not part of this by-id read cluster. This issue is fixed in version 5.2.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-55551https://github.com/infonl/dimpact-zaakafhandelcomponent/security/advisories/GHSA-cv9m-35q4-cxfmhttps://github.com/infonl/dimpact-zaakafhandelcomponent/pull/6225https://github.com/infonl/dimpact-zaakafhandelcomponent/pull/6229https://github.com/infonl/dimpact-zaakafhandelcomponent/commit/7b90586be658cec9fa5c98c0838636237f40931fhttps://github.com/infonl/dimpact-zaakafhandelcomponent/commit/d050f247301a1bcfb867015725a693c540a06f5ahttps://github.com/infonl/dimpact-zaakafhandelcomponent/releases/tag/v5.2.0#infonl #dimpact-zaakafhandelcomponent#CVE_2026_55551#bot", "url": "https://infosec.exchange/users/cve/statuses/117530906544126227"}, {"timestamp": "2026-10-30T17:17:25.647Z", "date_only": false, "value": "2026-10-30T17:17:25.647", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55551", "record": "FKIE_CVE-2026-55551", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-06T16:26:38.606Z", "date_only": false, "value": "2026-11-06T16:26:38.606916Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-55551", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-11-06T16:26:38.606Z", "date_only": false, "value": "2026-11-06T16:26:38.606916Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55551", "record": "FKIE_CVE-2026-55551", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-11-06T16:26:56.545Z", "date_only": false, "value": "2026-11-06T16:26:56.545Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-55551", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-06T16:26:56.545Z", "date_only": false, "value": "2026-11-06T16:26:56.545Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-55551", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-06T17:18:29.563Z", "date_only": false, "value": "2026-11-06T17:18:29.563", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55551", "record": "FKIE_CVE-2026-55551", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-13T15:41:09.627Z", "anchors": {"origin": {"timestamp": "2026-10-30T16:48:51.352Z", "date_only": false, "value": "2026-10-30T16:48:51.352Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55551", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-30T16:48:51.352Z", "date_only": false, "value": "2026-10-30T16:48:51.352Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55551", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 1205538.275326, "hours": 334.8717431461111, "days": 13.95298929775463, "min_seconds": 1205538.275326, "max_seconds": 1205538.275326, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-30T16:48:51.352Z", "date_only": false, "value": "2026-10-30T16:48:51.352Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55551", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-13T15:41:09.627Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
