CVE-2025-54376

CVE-2025-54376 is a high-severity improper authentication vulnerability in github.com/SpectoLabs/hoverfly (go), affecting versions < 1.12.0. It is fixed in 1.12.0.

Summary

WebSocket endpoint /api/v2/ws/logs reachable without authentication even when --auth is enabled

Impact

Authentication bypass; an attacker receives full application logs, including proxied request/response bodies, tokens, file paths, etc.

The application does not adequately verify the identity of a user, device, or process before granting access. Typical impact: unauthorized access to functions or data reserved for authenticated parties.

Affected versions

github.com/SpectoLabs/hoverfly (< 1.12.0)

Security releases

github.com/SpectoLabs/hoverfly → 1.12.0 (go)

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

  1. What is CVE-2025-54376? CVE-2025-54376 is a high-severity improper authentication vulnerability in github.com/SpectoLabs/hoverfly (go), affecting versions < 1.12.0. It is fixed in 1.12.0. The application does not adequately verify the identity of a user, device, or process before granting access.
  2. Which versions of github.com/SpectoLabs/hoverfly are affected by CVE-2025-54376? github.com/SpectoLabs/hoverfly (go) versions < 1.12.0 is affected.
  3. Is there a fix for CVE-2025-54376? Yes. CVE-2025-54376 is fixed in 1.12.0. Upgrade to this version or later.
  4. Is CVE-2025-54376 exploitable, and should I be worried? Whether CVE-2025-54376 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.

  5. What actually determines whether CVE-2025-54376 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.
  6. How do I fix CVE-2025-54376? Upgrade github.com/SpectoLabs/hoverfly to 1.12.0 or later.
