Summary

A symlink-retarget TOCTOU race in writeFileWithinRoot could point an attacker-controlled path alias outside the configured root between resolution and write operations.

Impact

Affected versions could cause out-of-root write side effects (including file creation or truncation) before final boundary validation.

Fix

Root-scoped write flow now opens existing files without pre-truncation, creates missing files with exclusive create semantics, truncates only after post-open identity/boundary checks, and removes out-of-root artifacts when a race is detected.
