Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The WebSocket API lacks rate limiting on authentication requests, enabling attackers to perform brute-force attacks against login endpoints and conduct denial-of-service attacks that can suppress or mis-route legitimate charger telemetry.

MitigationImplement rate limiting on WebSocket authentication endpoints with appropriate request thresholds and lockout policies to prevent brute-force and DoS attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify exposed WebSocket API endpoints
    Review your publicly accessible API endpoints and documentation to determine if WebSocket endpoints are enabled and accessible. Check for ws:// or wss:// URL patterns in your service configurations.
    Affected if WebSocket endpoints are exposed without authentication rate limiting controls
  2. Locate WebSocket authentication configuration
    Search configuration files for WebSocket server settings related to authentication handling. Look for terms like 'websocket', 'auth', 'rate-limit' in your service configuration directories.
    Affected if No rate limiting parameters are defined for WebSocket auth endpoints
  3. Verify rate limiting on auth endpoints
    Inspect rate limiting middleware or configuration for WebSocket upgrade/authentication paths. Compare against documented rate limit settings for other API authentication methods.
    Affected if Rate limiting is absent or set to excessively permissive values for WebSocket auth requests
  4. Check authentication attempt monitoring
    Review logs and monitoring for WebSocket connection attempts to authentication endpoints. Determine if there are controls to detect or block repeated failed authentication attempts.
    Affected if No mechanism exists to detect or throttle repeated failed WebSocket auth attempts
  5. Assess WebSocket connection handling
    Examine WebSocket connection lifecycle management configuration. Look for limits on concurrent connections, connection duration, and ability to suppress or mis-route telemetry.
    Affected if No connection limits or DoS protections are configured on WebSocket handlers

Your environment is affected if you have exposed WebSocket API endpoints without rate limiting configured on authentication requests.
