Summary
Sensitive Information Exposure Through Insecure Logging For Secrets Like Metadata.DockerBuildArgs
The AWS Serverless Application Model (SAM) CLI is an open source tool that allows customers to build, deploy and test their serverless applications built on AWS. AWS SAM CLI can build container (Docker) images and customers can specify arguments in the SAM template that are passed to the Docker engine during build [1].
References
If you have any questions or comments about this issue, we ask that you contact AWS/Amazon Security via our vulnerability reporting page [2] or directly via email to [email protected]. Please do not create a public GitHub issue.
Impact
If customers specify sensitive data in the DockerBuildArgs parameter of their template, the sensitive data will be shown in clear text in the AWS SAM CLI output via STDERR when running the sam build command.
GHSA-RJC6-VM4H-85CG has a CVSS score of 4.8 (Medium). The vector is network-reachable, low privileges required, and user interaction required. 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 (1.122.0); 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.

A patch is included in aws-sam-cli>=1.122.0.
We strongly recommend customers install AWS SAM CLI v1.122.0 or above. Please review logs produced by your SAM CLI runs if you have used the DockerBuildArgs parameter and consider rotating the secrets if you believe they were exposed.
Frequently Asked Questions
- What is GHSA-RJC6-VM4H-85CG? GHSA-RJC6-VM4H-85CG is a medium-severity security vulnerability in aws-sam-cli (pip), affecting versions < 1.122.0. It is fixed in 1.122.0.
- How severe is GHSA-RJC6-VM4H-85CG? GHSA-RJC6-VM4H-85CG has a CVSS score of 4.8 (Medium). 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 aws-sam-cli are affected by GHSA-RJC6-VM4H-85CG? aws-sam-cli (pip) versions < 1.122.0 is affected.
- Is there a fix for GHSA-RJC6-VM4H-85CG? Yes. GHSA-RJC6-VM4H-85CG is fixed in 1.122.0. Upgrade to this version or later.
- Is GHSA-RJC6-VM4H-85CG exploitable, and should I be worried? Whether GHSA-RJC6-VM4H-85CG 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 GHSA-RJC6-VM4H-85CG 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.
- How do I fix GHSA-RJC6-VM4H-85CG? Upgrade
aws-sam-clito 1.122.0 or later.
