CyberRota Analysis
AI-GeneratedOpenReception's appointment booking software prior to version 1.0.2 is vulnerable due to the ability of a TENANT_ADMIN to store unfiltered `javascript:` URLs in tenant configuration links, which are then rendered on the patient-facing landing page. This flaw allows attackers to execute malicious JavaScript in the patient's browser, potentially compromising sensitive form data before client-side encryption is applied, undermining the platform's security model. Healthcare organizations using this software should prioritize updating to version 1.0.2 to mitigate this high-severity risk.

Original NVD Description
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, a TENANT_ADMIN can store `javascript:` URLs in the tenant `links` configuration (`website`, `imprint`, `privacyStatement`). These values are returned to the patient-facing landing page via `/api/public`, hydrated into the SvelteKit Button component, and rendered as `<a href="javascript:...">` elements without URL-scheme filtering. A patient who clicks any such link executes the attacker's JavaScript inside the patient browser origin, where patient form data is read before client-side encryption is applied. This breaks the project's central trust claim that the server is an untrusted relay and that administrators cannot read patient data. Patient-side encryption happens after form input, so JavaScript executing in the patient origin can read or alter the plaintext before encryption is performed. Version 1.0.2 fixes the issue.
