CVE-2026-42952
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 · uneditedPreviously, there was no throttling on repeated authentication attempts to the charging station backend, which could allow an attacker to execute a denial-of-service attack.
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 · moderate confidenceThe charging station backend lacks rate limiting on authentication endpoints, allowing attackers to flood the system with repeated login attempts. This can exhaust resources and cause denial of service for legitimate users.

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 checksWork through these to decide whether this CVE applies to you.
-
Check authentication endpoint configuration for rate limitingReview the backend configuration files (e.g., authentication config, API gateway settings, or web server config) for any rate limiting, throttling, or request frequency限制 settings on login/authentication endpoints.Affected if No rate limiting or throttling configuration is found on authentication endpoints
-
Test for throttling on repeated login attemptsSend multiple repeated authentication requests (e.g., 10+ failed login attempts in quick succession) from a test client or script to the login endpoint and observe whether the system blocks, delays, or throttles subsequent requests.Affected if The system accepts all requests without imposing any throttling, delay, or temporary block after repeated attempts
-
Verify account lockout or CAPTCHA policies existCheck the authentication system configuration or documentation for account lockout policies (e.g., lock after N failed attempts) or CAPTCHA challenges on login endpoints.Affected if No account lockout policy or CAPTCHA challenge is configured on authentication endpoints
-
Review load balancer or proxy rate limiting rulesIf a load balancer, API gateway, or reverse proxy sits in front of the charging station backend, inspect its configuration for any rate limiting rules targeting the authentication endpoints.Affected if No rate limiting rules are defined at the infrastructure layer for authentication endpoints
The environment is affected if authentication endpoints lack rate limiting, throttling, or account lockout mechanisms and allow unlimited repeated login attempts without restriction.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement throttling mechanisms such as rate limiting, account lockout policies, or CAPTCHA challenges on authentication endpoints to restrict the number of failed attempts within a given time window.
