High-confidence secret in CodeBuild PLAINTEXT environment variable

Severity: Critical
Service: Secrets exposure
Check ID: SECRETS_CODEBUILD_ENV_HIGH

What this check finds

A CodeBuild project PLAINTEXT environment variable matches a high-confidence credential pattern. PLAINTEXT env vars are visible in build logs and readable by any principal with codebuild:BatchGetProjects. Use PARAMETER_STORE or SECRETS_MANAGER types instead.

Passing looks like: No secrets in CodeBuild environment variables.

How to fix it

Change the environment variable type from PLAINTEXT to PARAMETER_STORE or SECRETS_MANAGER in the CodeBuild project configuration and store the value in SSM SecureString or Secrets Manager.

Compliance controls it is evidence for

A failing result counts against these controls in KloudLytics; a passing one is evidence towards them. How compliance mapping works

Checked on every scan

KloudLytics runs this check each time it scans a connected AWS account, through a read-only role, and lists every affected resource with its region. On Pro and Business a fix is written for the specific resource rather than the general case above. The exact access it needs
