What is CVE-2022-38149?

CVE-2022-38149 is a high-severity security vulnerability in github.com/hashicorp/consul-template (go), affecting versions < 0.27.3. It is fixed in 0.27.3, 0.28.3, 0.29.2.

How severe is CVE-2022-38149?

CVE-2022-38149 has a CVSS score of 7.5 (High). 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.

Which versions of github.com/hashicorp/consul-template are affected by CVE-2022-38149?

github.com/hashicorp/consul-template (go) versions < 0.27.3 is affected.

Is there a fix for CVE-2022-38149?

Yes. CVE-2022-38149 is fixed in 0.27.3, 0.28.3, 0.29.2. Upgrade to this version or later.

Is CVE-2022-38149 exploitable, and should I be worried?

Whether CVE-2022-38149 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-2022-38149 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.

Summary

HashiCorp Consul Template could reveal Vault secret contents in error messages

In HashiCorp Consul Template through version 0.29.1, invalid templates could inadvertently reveal the contents of Vault secret in errors returned by the *template.Template.Execute 5 method, when given a template using Vault secret contents incorrectly. This method has been updated to redact Vault secrets when creating an error string, making it safe to log the error.. This issue was fixed in version 0.29.2.

Impact

CVE-2022-38149 has a CVSS score of 7.5 (High). 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. A fixed version is available (0.27.3, 0.28.3, 0.29.2); upgrading removes the vulnerable code path.

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.
