Summary

CVE-2026-25114 is a high-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Cloudcharge Cloudcharge.Se. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 28.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-7 (Unsuccessful Logon Attempts) and SC-5 (Denial-of-service Protection).

Threat & Defense at a Glance

What attackers do: exploitation maps to Brute Force (T1110) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-7 Unsuccessful Logon Attempts good match

prevent

Directly enforces limits on consecutive unsuccessful authentication attempts, mitigating brute-force attacks enabled by unrestricted authentication requests.

SC-5 Denial-of-service Protection good match

prevent

Provides denial-of-service protection mechanisms such as rate limiting to prevent flooding of the WebSocket API with excessive authentication requests that suppress legitimate telemetry.

AC-10 Concurrent Session Control partial match

prevent

Limits concurrent sessions to mitigate resource exhaustion from multiple simultaneous WebSocket connections attempting excessive authentication.

MITRE ATT&CK Enterprise TechniquesAI

T1110 Brute Force Credential Access

Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

attack.mitre.org →

T1499.002 Service Exhaustion Flood Impact

Adversaries may target the different network services provided by systems to conduct a denial of service (DoS).

attack.mitre.org →

Why these techniques?

Lack of rate limiting on authentication requests directly enables brute-force credential access (T1110) and service exhaustion DoS via flooding (T1499.002).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

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…

Deeper analysisAI

CVE-2026-25114 is a vulnerability in the WebSocket Application Programming Interface that lacks restrictions on the number of authentication requests due to the absence of rate limiting. Published on 2026-02-27, it affects components handling charger telemetry and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), mapped to CWE-307 (Improper Restriction of Excessive Authentication Attempts).

Unauthenticated remote attackers can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation enables denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or brute-force attacks to achieve unauthorized access, with primary impact on availability.

CISA ICS Advisory ICSA-26-057-03, along with its CSAF representation on GitHub and the vendor contact page at https://cloudcharge.tech/support/contact/, provide further details on mitigations. Security practitioners should consult these resources for patch information and recommended actions.
