Línea de trabajo

Start in rust/crates/runtime/src/file_ops.rs at read_file, then inspect normalize_path and validate_workspace_boundary. Verify that the resolved path is checked against workspace_root before reading, including traversal and symlink escape cases; the issue is done when out-of-workspace reads are rejected while valid workspace reads still work.

File: rust/crates/runtime/src/file_ops.rs
Location: read_file


What's wrong

The function reads a file path supplied by the caller without checking that it stays inside the intended workspace. The line let absolute_path = normalize_path(path)?; resolves the user‑provided path to an absolute path, but no subsequent call to validate_workspace_boundary is made, so a malicious caller can traverse out of the workspace (e.g., using ../ or symlinks) and read any file the process can access.

Suggested fix

Validate the resolved path against the workspace root before reading the file. For example:

pub fn read_file(
    path: &str,
    offset: Option<usize>,
    limit: Option<usize>,
    workspace_root: &Path,
) -> io::Result<ReadFileOutput> {
    let absolute_path = normalize_path(path)?;
    // Ensure the path stays within the workspace
    validate_workspace_boundary(&absolute_path, workspace_root)?;
    // ... rest of the function unchanged ...
}
