CVE-2020-26230 allowed for the identification and de-anonymization of COVID-19 positive users of Spain's Radar COVID exposure notification app. The vulnerability stemmed from the fact that only positive users' apps connected to the backend server, enabling on-path observers (like ISPs or MNOs) to identify infected individuals. With a CVSS score of 5.3 (Medium), the attack required high complexity and user interaction to achieve high confidentiality impact. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability, which has since been mitigated by injecting dummy traffic from all users.
