CVE-2026-48085: CWE-862: Missing Authorization in open-reception appointment-booking-software
OpenReception appointment booking software prior to version 1.0.1 contains a critical missing authorization vulnerability. An unauthenticated attacker can create additional global administrator accounts via a POST request to the /setup/create-admin-account endpoint, bypassing checks that an admin already exists. These accounts are created active and immediately usable without email confirmation. The vulnerability allows full platform-level administrative control without authentication. The issue is fixed in version 1.0.1.
AI Analysis
Technical Summary
OpenReception's appointment booking software before version 1.0.1 allows unauthenticated network attackers to create multiple GLOBAL_ADMIN accounts by sending POST requests to the /setup/create-admin-account endpoint. The endpoint does not verify if an admin account already exists, and the protection on the setup page only redirects GET requests, not POST requests. The created admin accounts are active immediately with full access and do not require email confirmation. This flaw enables full administrative control of the platform without authentication or user interaction. The vulnerability is distinct from the initial deployment race condition and can be exploited post-deployment. There is no rate limiting on account creation, and the same-origin check only protects against browser-based CSRF, but can be bypassed by tools that set the Origin header. Users are advised to upgrade to version 1.0.1 where this issue is patched.
Potential Impact
An unauthenticated attacker can gain full administrative control over the OpenReception platform by creating active global admin accounts without any verification or user interaction. This compromises confidentiality, integrity, and availability of the system, allowing complete platform takeover. The vulnerability has a CVSS score of 9.8 (critical).
Mitigation Recommendations
Upgrade OpenReception appointment booking software to version 1.0.1 or later, where this vulnerability is fixed. No other mitigations are documented. Until patched, restrict network access to the /setup/create-admin-account endpoint to trusted users only.
