Vulnerability in OpenReception (CVE-2026-48085)

Summary

Vulnerability in OpenReception (CVE-2026-48085). Successful exploitation can lead to full system takeover. Exploitable via default.

Original description

The description as published by the source.

OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. 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…

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify
    grep -r 'OpenReception' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で OpenReception を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Post-deployment verification verify
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
