## Framework Template Path Traversal Risk: Plugin Trust Boundary Blurred, Defense-in-Depth Urged
A subtle but critical design flaw in a Python framework's template loading system creates a potential path traversal risk, exposing a blurred trust boundary between the framework and its plugins. The current implementation resolves template file paths relative to a plugin's configuration directory but fails to scope them, meaning a plugin could theoretically define a template pointing to a sensitive system file like `/etc/passwd`. While the immediate risk is mitigated because plugins are currently considered trusted code installed via Python entry points, the absence of a technical guardrail makes the trust assumption dangerously implicit rather than explicit.

The core issue is in the path resolution logic. A plugin's TOML configuration can specify a template file with a relative path like `../../../etc/passwd`. The framework's resolver, as described in issue #190, would follow this path upward out of the plugin's designated directory, potentially accessing any file on the filesystem the process has permissions to read. This is not a present-day exploit but a latent architectural vulnerability. The proposal is to implement a scoping check within the `load_framework_config` function and related helpers to confine resolved paths strictly within the plugin's own directory tree, making any attempt at traversal an explicit error.

This fix is framed as essential defense-in-depth. It serves two strategic purposes: first, it makes the security contract visible to plugin developers, clarifying that their template resources are scoped to their package. Second, it future-proofs the framework against a potential expansion of its plugin ecosystem. If the system ever evolves to support loading plugins from less-trusted sources—such as remote registries or user-uploaded configurations—the traversal guard will already be in place, preventing a costly and risky retrofit. The absence of this check leaves a silent backdoor open in the framework's security model.
