CVE-2026-48081Public exploitNetwork attack vector

Patient data theft via unsafe tenant links

Published Aug 6, 2026 · Updated Aug 6, 2026

Stored XSS in OpenReception before 1.0.2 allows remote authenticated users to read or alter patient data through crafted tenant links. Tenant link updates accept javascript: schemes, and the public API passes them to SvelteKit Button href attributes without scheme filtering. A TENANT_ADMIN must save a link and a patient must click it; the script then runs in the patient origin before form data or PINs are encrypted.
