Trivy Terraform filesystem functions read paths above the scan root

Fixed in: Trivy 0.71.0

patched

details

Finding IDs: F-TRIVY-TF-FILE-001
CVE: CVE-2026-104994
Status: patched
Fixed in: Trivy 0.71.0
Note: The published CVE covers Trivy before 0.71.0 when Terraform filesystem functions access paths above the scan root during misconfiguration scanning of untrusted input. Exposure requires sensitive data at an unintended path and visibility of that value in scan output. The vendor advisory GHSA-87hp-4m93-274g remains closed and is not presented as a published advisory.

Finding IDs: F-TRIVY-TF-FILE-001
Status: fixed in Trivy v0.71.0+
Reported via: security contact
Note: revalidated with a minimal Terraform file("../secret.txt") PoC through mapfs.WithUnderlyingRoot: Trivy v0.70.0 reads POC_SECRET from outside the scan root, while v0.71.0 and v0.71.2 block traversal with no file exists at ../secret.txt. upstream fix commit 9d91b888cf63 shipped in v0.71.0 and makes Terraform filesystem functions use a sandboxed FS without access to the underlying OS root. CVE-2026-104994 was published on 2026-10-02 for this Terraform filesystem-function issue.
