CVE-2026-9509 (GCVE-0-2026-9509)

Vulnerability from cvelistv5 – Published: 2026-05-29 12:11 – Updated: 2026-05-29 13:33

Title
Uncaught exception vulnerability in Suprema's BioStar
Summary
An unhandled exception in Suprema BioStar 2 (Server), versions 2.9.8, 2.9.10, and 2.9.11, that allows an unauthenticated remote attacker to cause a denial of service (DoS) by sending HTTP POST requests to the ‘/api/migration’ endpoint. This request triggers a failure that halts critical processes, leaving the system offline until the services or server are manually restarted. As a result, access control readers cease to function, and potential failures may occur in third-party integrations. Since the exploit requires no privileges or user interaction and is trivial to automate, the impact on availability is high, and the effect extends to interconnected systems.

CVE-2026-9508 (GCVE-0-2026-9508)

Vulnerability from cvelistv5 – Published: 2026-05-29 12:09 – Updated: 2026-05-29 13:33

Title
Incorrect Permission Assignment for Critical Resource vulnerability in Suprema's BioStar
Summary
Incorrect permission settings on a critical resource in Suprema BioStar 2 (versions 2.9.3 through 2.9.11) that allow backup files to be publicly exposed when the administrator configures their path within the NGINX webroot. This vulnerability allows an attacker with network access to directly download backup ZIP files via ‘http(s)://[server]/download/…’ without requiring authentication. This exposes highly sensitive information that can lead to server impersonation, unauthorized access to databases, and lateral movement.
Severity
10 (Critical)
