CVE-2026-52866

BLE service interruption via unauthenticated slot monopolization

Published Jun 18, 2026 · Updated Jun 18, 2026

Missing authorization in Apollo Pharmacy APG-01 BT 0x0110_v1.1.0 allows physically proximate attackers to interrupt BLE access. The device allocates its only BLE connection slot without authorizing the connecting client, allowing that client to keep the slot occupied. Bluetooth Low Energy range is required, and the reported consequence is loss of connectivity rather than data exposure or modification.
