CVSS v3.1

Official Description

This vulnerability occurs when a WebSocket endpoint does not enforce

proper authentication mechanisms, allowing unauthorized users to

establish connections. As a result, attackers can exploit this weakness

to gain unauthorized access to sensitive data or perform unauthorized

actions. Given that no authentication is required, this can lead to

privilege escalation and potentially compromise the security of the

entire system.

Risk Analysis

EVMapa contains a WebSocket endpoint that lacks authentication, allowing unauthorized users to establish connections. This can lead to privilege escalation and unauthorized access to sensitive data. The critical CVSS score indicates a high risk of total system compromise.

No public exploit is known, and the vulnerability is not in the CISA KEV. It is remotely exploitable.

Recommended Action

Enforce robust authentication mechanisms on all WebSocket endpoints. Restrict access to authorized users only.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2025-54816 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
