What is CVE-2026-50244?
CVE-2026-50244 is a medium-severity missing authorization vulnerability in Naxclow Smart Doorbell X3, published on 12 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Naxclow platform exposes a registration endpoint that accepts signed requests containing a batch prefix and an arbitrary caller-supplied account identifier, without validating any ownership relationship. Each call mints a new sequential device identifier and returns the current high-water counter value for the batch, allowing callers to measure and enumerate the active device space. The endpoint’s behavior enables precise fleet enumeration.
