open-computer-use through commit 610bac8 contains a stored cross-site scripting vulnerability in Logger.write_log_file in os_computer_use/logging.py, which writes transcript text into log.html without HTML escaping. Attackers controlling sandbox content, such as web pages or files appearing in run_command output, can inject script that runs when operators open the log, exfiltrating transcript contents.
