How to Fix GHSA-wpr2-j6gr-pjw9

To remediate this vulnerability, upgrade all affected Github.com/opentofu/opentofu dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/opentofu/opentofu fixed: 1.8.3 
Upgrade github.com/opentofu/opentofu to 1.8.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/opentofu/opentofu

How to Check if You Are Affected

To determine whether your application is affected by GHSA-wpr2-j6gr-pjw9, inspect your project dependencies for Github.com/opentofu/opentofu:

inspect dependencies for github.com/opentofu/opentofu

Analyze the terminal output to locate any version of Github.com/opentofu/opentofu in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.8.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Github.com/opentofu/opentofu, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Users who have opted into static evaluation of module sources, versions, and backend configurations may be at risk of exposing sensitive variables and locals. This is a workflow that should not be possible and explicitly show errors. ### Workarounds Check that you are not using sensitive variables in module sources and versions, as well as backend configurations. The patch will add explicit errors and prevent this from being possible. ### Examples ```hcl variable "backend_path" { type = string sensitive = true } terraform { backend "local" { path = var.backend_path } } ``` ```hcl variable "mod_info" { type = string sensitive = true } module "foo" { source = var.mod_info //version = var.mod_info } ```
