Infracost provides cloud cost intelligence for engineers, AI coding agents, and CI/CD.

MEDIUM 5.9EPSS 0.43%

Does this matter?

Lower severity and a low EPSS score (0.43%). Track it; it rarely justifies an emergency change on its own.

Description

Infracost provides cloud cost intelligence for engineers, AI coding agents, and CI/CD. Prior to 0.10.45, the readFile, pathExists, isDir, and matchPaths template functions in internal/config/template/parser.go use a lexical filepath.Rel check and a leaf-only os.Lstat check that do not resolve an intermediate directory symlink. A repository can contain a path such as evil/file where evil points outside the checkout, causing os.ReadFile and related operations to follow the symlink and read runner-accessible files. The resulting content is rendered into generated configuration and can be surfaced through the Infracost dashboard or pull request comment, with greater impact in workflows that provide repository secrets. This issue is fixed in version 0.10.45.
