제출 #811428: continuedev continue v1.2.22-vscode Path Traversal (CWE-22)

# Technical Details
A Path Traversal vulnerability exists in the `lsToolImpl` method in `core/tools/implementations/lsTool.ts` of Continue.

The application fails to apply standard workspace boundary checks and explicitly overrides default security blocklists, allowing unauthenticated enumeration of the host system.

# Vulnerable Code
File: core/tools/implementations/lsTool.ts
Method: lsToolImpl
Why: The `lsTool` function omits calling the explicit `throwIfFileIsSecurityConcern(resolvedPath.displayPath)` security barrier used by other file manipulation functions. Furthermore, it explicitly overrides protective environment blocklists by utilizing the configuration `overrideDefaultIgnores: ignore()`.

# Reproduction
1. Establish an external JSON-RPC connection to the Continue Core TCP server port (e.g., 3000).
2. Send a `tools/call` message JSON payload targeting the `ls` system function.
3. Inject the `dirPath` variable argument with an absolute, restricted directory path, such as `/etc`.
4. Observe the comprehensive file/directory listing of the restricted path returned in the JSON response payload.

# Impact
- Unauthorized local file enumeration exposing directory structures.
- Leakage of sensitive software configurations or user configurations (e.g., `~/.ssh/`, `.env`) that can be chained to increase exploit impact.
