CVE-2026-88394

WookTeam v1.6.6 and before is vulnerable to a Directory Traversal. The project task export endpoint /api/project/task/export downloads an arbitrary file from the server when the data parameter is supplied with a crafted JSON payload. The file value inside the JSON is concatenated directly into storage path($file) without any path normalization or directory boundary check, so directory traversal (../) escapes the storage/ directory and response()->download() streams any file readable by the web server process.
