Prior to 1.7.2-beta-1, guest users can approve or reject quotes belonging to any client, not just their assigned clients. The `approve()` and `reject()` methods in the Guest Quotes controller, `application/modules/guest/controllers/Quotes.php`, call `approve_quote_by_id($quote_id)` and `reject_quote_by_id($quote_id)` directly without the `where_in('ip_quotes.client_id', $this->user_clients)` scoping that sibling methods use. A guest user assigned to one client can change another client's quote status by supplying sequential integer `quote_id` values, and `email_quote_status()` also sends notification emails. Additionally, `generate_pdf()` calls `mark_viewed($quote_id)` before checking the client scope, allowing a guest user to mark another client's quote as viewed. These issues are fixed in version 1.7.2-beta-1 and the subsequent stable version 1.7.2.\nhttps://www.cve.org/CVERecord?id=CVE-2026-55561https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-6xj3-274m-4mvghttps://github.com/InvoicePlane/InvoicePlane/pull/1413https://github.com/InvoicePlane/InvoicePlane/pull/1471https://github.com/InvoicePlane/InvoicePlane/commit/424dc44eb54030b93176bb08cba07ba12d7ae451https://github.com/InvoicePlane/InvoicePlane/commit/fca7792a24de0a749d881cbbe4af6f58e9545d20https://github.com/InvoicePlane/InvoicePlane/releases/tag/v1.7.2https://github.com/InvoicePlane/InvoicePlane/releases/tag/v1.7.2-beta-1#InvoicePlane#CVE_2026_55561#bot", "url": "https://infosec.exchange/users/cve/statuses/117520943807966491"}, {"timestamp": "2026-10-28T23:17:10.350Z", "date_only": false, "value": "2026-10-28T23:17:10.350", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55561", "record": "FKIE_CVE-2026-55561", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, {"timestamp": "2026-10-28T23:17:10.480Z", "date_only": false, "value": "2026-10-28T23:17:10.480", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55561", "record": "FKIE_CVE-2026-55561", "field": "lastModified"}], "metrics": {"as_of": "2026-10-31T11:56:03.144Z", "anchors": {"origin": {"timestamp": "2026-10-28T22:33:47.140Z", "date_only": false, "value": "2026-10-28T22:33:47.140Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55561", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-28T22:33:47.140Z", "date_only": false, "value": "2026-10-28T22:33:47.140Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55561", "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": 220936.004869, "hours": 61.37111246361111, "days": 2.557129685983796, "min_seconds": 220936.004869, "max_seconds": 220936.004869, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-28T22:33:47.140Z", "date_only": false, "value": "2026-10-28T22:33:47.140Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-55561", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-31T11:56:03.144Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
