Prior to version 1.0.1, a fully provisioned OpenReception instance accepts unauthenticated POST requests to `/setup/create-admin-account` and creates additional GLOBAL_ADMIN accounts without verifying that an admin already exists. Any unauthenticated network attacker who can submit a same-origin form POST gains full platform-level administrative control. The newly created account is `is_active=true` with `confirmation_state=ACCESS_GRANTED` and does not require completing email confirmation; the GLOBAL_ADMIN row is created active and immediately usable. Login and tenant enumeration succeed without any further interaction. This is distinct from the deployment race condition already documented on the `Claiming an instance` page. That documented race covers the window between deployment and first claim. The bug reported here works after the operator has properly claimed and configured the instance: the layout-level guard that protects the setup page only redirects on GET, while the `default` form action handler creates the user without rechecking `adminExists()`. Three GLOBAL_ADMIN accounts were created in succession during testing, with no rate limiting observed. Audit-specific event logging beyond standard application logs was not assessed; the standard `[error]` line that surfaces only when a uniqueness conflict is hit is not the same as a security event for \"additional admin created post-claim\". The form post is rejected for browser drive-by CSRF by SvelteKit's built-in same-origin check, but any tool that supplies a matching `Origin` header (curl, Burp, automated scanners, server-side proxies) bypasses this trivially. No additional preconditions exist. Users should upgrade to version 1.0.1 to receive a patch.","state":"PUBLISHED","assigner":"GitHub_M","published_at":"2026-08-06 22:17:11","updated_at":"2026-08-07 16:17:24"},"problem_types":["CWE-862","CWE-862 CWE-862: Missing Authorization"],"metrics":[{"version":"3.1","source":"security-advisories@github.com","type":"Secondary","score":"9.8","severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"}},{"version":"3.1","source":"CNA","type":"DECLARED","score":"9.8","severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":9.8,"baseSeverity":"CRITICAL","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}}],"references":[{"url":"https://github.com/open-reception/appointment-booking-software/commit/222408af6fd4bd85554a25ec8de8131bd0733797","name":"https://github.com/open-reception/appointment-booking-software/commit/222408af6fd4bd85554a25ec8de8131bd0733797","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-qvvq-hhpj-64rp","name":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-qvvq-hhpj-64rp","refsource":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-48085","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48085","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"open-reception","product":"appointment-booking-software","version":"affected < 1.0.1","platforms":[]}],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"adp":[{"metrics":[{"other":{"content":{"id":"CVE-2026-48085","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","timestamp":"2026-08-07T15:37:56.257398Z","version":"2.0.3"},"type":"ssvc"}}],"providerMetadata":{"dateUpdated":"2026-08-07T15:39:38.560Z","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP"},"references":[{"tags":["exploit"],"url":"https://github.com/open-reception/appointment-booking-software/security/advisories/GHSA-qvvq-hhpj-64rp"}],"title":"CISA ADP Vulnrichment"}],"cna":{"affected":[{"product":"appointment-booking-software","vendor":"open-reception","versions":[{"status":"affected","version":"< 1.0.1"}]}],"descriptions":[{"lang":"en","value":"OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform.
