CVE-2026-30368Public exploitNetwork attack vector

Unauthenticated device control via client-generated tokens

Published Apr 24, 2026 · Updated Apr 24, 2026

Incorrect authorization in Lightspeed Classroom 5.1.2.1763770643 allows remote attackers to control and monitor student devices. The browser extension generates authorization tokens in client-side WebAssembly and trusts spoofable Chrome identity and worker-integrity checks, allowing a harness to mint a victim-bound token from an email address and district ID. No Lightspeed credentials or device access is required; screen viewing additionally depends on class schedules and campus-network policy.
