Prior to version 2.0.0, the account-confirmation link in emails is built from the request Host header, with no allowlist. The unauthenticated POST /api/auth/resend-confirmation rotates a pending invitee's confirmation token and emails a link whose host comes from the request. An attacker who sends one resend-confirmation with Host: attacker.example and a pending invitee's email causes that invitee to receive a confirmation email whose only link points to the attacker. If the invitee clicks, the one-time confirmation token reaches the attacker, who then confirms the account on the real tenant domain and registers a passkey they control, taking over the account before the legitimate invitee ever uses it. All released versions through v1.1.0 are affected; no patched version exists yet. Reaching the app with a spoofed Host depends on the front proxy: the stock Caddy catch-all forwards it, while an operator who configures explicit per-tenant proxy blocks is not affected (see Details 4). The invite path builds links from the trusted tenant.domain (invite/+server.ts:204-210); the resend-confirmation path builds them from the request Host. This issue has been patched in version 2.0.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-58202https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-w5g9-g2p4-2g4mhttps://github.com/open-reception/appointment-booking-software/commit/df5432776a1a5b47c3a64d64e9d05dbe2b7a7819https://github.com/open-reception/appointment-booking-software/releases/tag/v2.0.0#open-reception #appointment-booking-software#CVE_2026_58202#bot", "url": "https://infosec.exchange/users/cve/statuses/117492152909339072"}, {"timestamp": "2026-10-23T21:17:24.473Z", "date_only": false, "value": "2026-10-23T21:17:24.473", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58202", "record": "FKIE_CVE-2026-58202", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-10-29T18:16:21.166Z", "date_only": false, "value": "2026-10-29T18:16:21.166284Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-58202", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-29T18:16:21.166Z", "date_only": false, "value": "2026-10-29T18:16:21.166284Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58202", "record": "FKIE_CVE-2026-58202", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-10-29T18:16:47.209Z", "date_only": false, "value": "2026-10-29T18:16:47.209Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-58202", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-29T18:16:47.209Z", "date_only": false, "value": "2026-10-29T18:16:47.209Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-58202", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-29T19:17:23.980Z", "date_only": false, "value": "2026-10-29T19:17:23.980", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58202", "record": "FKIE_CVE-2026-58202", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-07T06:09:50.920Z", "anchors": {"origin": {"timestamp": "2026-10-23T20:27:36.090Z", "date_only": false, "value": "2026-10-23T20:27:36.090Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58202", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-23T20:27:36.090Z", "date_only": false, "value": "2026-10-23T20:27:36.090Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58202", "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": 1244534.830247, "hours": 345.70411951305556, "days": 14.404338313043983, "min_seconds": 1244534.830247, "max_seconds": 1244534.830247, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-23T20:27:36.090Z", "date_only": false, "value": "2026-10-23T20:27:36.090Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58202", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-07T06:09:50.920Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
