🔗 Proof
|
CVE-2026-8374 demonstrates that Bluetooth pairing on the SwitchBot Lock line relies on weak initialization vectors and unsafe primitives, indicating brand-wide weaknesses in BLE session protection.

Overall assessment: Risk for the Curtain 3 comes from brand-level findings rather than model-specific ones. Four SwitchBot CVEs are tracked, the most severe being CVE-2024-48786 (CVSS 9.1, information exposure through the firmware update process) and CVE-2026-8374 (weak IVs and unsafe primitives in Bluetooth pairing, from Neodyme research on the Lock line). None of them appear in CISA KEV and all have EPSS below 1%, so active exploitation is not observed, and the vendor does ship OTA updates - notably version 2.01.078 which removed the Telnet debug code. The device itself is BLE-only for direct control and relies on a SwitchBot Hub for cloud access, which limits remote exposure.
