About Ev.Energy

CVE-2026-24445 affects Ev.Energy, a product from Ev.Energy. Before acting, confirm where Ev.Energy runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.

What the flaw is

In plain terms: 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.

Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it

  • Inventory every instance of Ev.Energy and record the running version against the affected range above.
  • Check external attack surface scans for internet facing instances of the component.
  • Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
  • Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.

How to fix it

  • Apply the fixed version of Ev.Energy named in the vendor advisory.
  • If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
  • Rescan after the change to prove the exposure is gone, then close the ticket.

CRITICAL9.3
CVE-2026-27772
Ev.Energy

WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

CVE-2026-110770
Product in advisory

Databasus 3.7.0 through 3.61.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to brute-force password reset codes via POST /api/v1/users/reset-password. Attackers can request a six-digit code for a known email, then guess it without rate limiting, lockout, or invalidation to take over accounts, including administrators.

Tenda W30e Firmware

Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) do not enforce rate limiting or account lockout mechanisms on authentication endpoints. This allows attackers to perform unrestricted brute-force attempts against administrative credentials.

CVE-2026-53997
Product in advisory

Netherman Portal del Hermano (portaldelhermano.es) before 2026-10-06 contains a broken authentication vulnerability in its password-recovery flow at the POST /password/create-access and POST /password/email endpoints, allowing unauthenticated attackers to take over any member account across all tenants by exploiting the lack of rate limiting and distinct error messages that act as oracles for each of the four identity-verification factors (DNI, date of birth, phone number, last four IBAN digits). Attackers can confirm the DNI via the oracle, brute-force the date of birth and IBAN digits, obtain the phone number through open-source intelligence, then submit an attacker-controlled email field so the password reset link is delivered to them, enabling full account takeover including profile data, full IBAN, and fiscal documents.

CVE-2026-33640
Getoutline Outline

Outline is a service that allows for collaborative documentation. Outline implements an Email OTP login flow for users not associated with an Identity Provider. Starting in version 0.86.0 and prior to version 1.6.0, Outline does not invalidate OTP codes based on amount or frequency of invalid submissions, rather it relies on the rate limiter to restrict attempts. Consequently, identified bypasses in the rate limiter permit unrestricted OTP code submissions within the codes lifetime. This allows attackers to perform brute force attacks which enable account takeover. Version 1.6.0 fixes the issue.

CVE-2026-33152
Tandoor Recipes

Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, Tandoor Recipes configures Django REST Framework with BasicAuthentication as one of the default authentication backends. The AllAuth rate limiting configuration (ACCOUNT_RATE_LIMITS: login: 5/m/ip) only applies to the HTML-based login endpoint at /accounts/login/. Any API endpoint that accepts authenticated requests can be targeted via Authorization: Basic headers with zero rate limiting, zero account lockout, and unlimited attempts. An attacker can perform high-speed password guessing against any known username. Version 2.6.0 patches the issue.
