Technical details

The write_text_file function in src/agentscope/tool/_text_file/_write_text_file.py fails to properly validate file path inputs, allowing directory traversal sequences (e.g., ../). An attacker with the ability to call this function can write arbitrary files to locations outside the intended workspace. No authentication or special privileges are required beyond the ability to invoke the vulnerable function.
