Summary
This vulnerability occurs when a WebSocket endpoint does not enforce proper authentication...
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.
Impact
A critical operation is accessible without requiring any authentication. Typical impact: any user can invoke the privileged function.
CVE-2025-54816 has a CVSS score of 9.4 (Critical). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-54816? CVE-2025-54816 is a critical-severity missing authentication for critical function vulnerability. No fixed version is listed yet. A critical operation is accessible without requiring any authentication.
- How severe is CVE-2025-54816? CVE-2025-54816 has a CVSS score of 9.4 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Is there a fix for CVE-2025-54816? No fixed version is listed for CVE-2025-54816 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-54816 exploitable, and should I be worried? Whether CVE-2025-54816 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-54816 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
