Title
OpenTofu before 1.8.3 Secret Variable Leaking via Static Evaluation
Summary
OpenTofu versions 1.8.0 through 1.8.2 do not properly restrict sensitive variables and locals when users have opted into static evaluation of module sources, versions, and backend configurations. As a result, values marked as sensitive may be exposed through these configuration elements instead of producing an error. This is fixed in OpenTofu 1.8.3, which adds explicit errors to prevent the use of sensitive values in these contexts.

Title
OpenTofu before 1.11.7 Symlink Following Path Traversal
Summary
OpenTofu before 1.11.7 fails to validate existing symlinks in the provider cache directory during initialization. Attackers can place a malicious symlink in a trusted working directory to cause tofu init to write provider package contents to arbitrary filesystem locations outside the working tree.

Title
OpenTofu before 1.8.3 Secret Variable Leaking via Static Evaluation
Summary
OpenTofu versions 1.8.0 through 1.8.2 do not properly restrict sensitive variables and locals when users have opted into static evaluation of module sources, versions, and backend configurations. As a result, values marked as sensitive may be exposed through these configuration elements instead of producing an error. This is fixed in OpenTofu 1.8.3, which adds explicit errors to prevent the use of sensitive values in these contexts.
