Hayabusa versions prior to 3.8.0 contain a cross-site scripting (XSS) vulnerability in its HTML report output that allows an attacker to execute arbitrary JavaScript when a user scans JSON-exported logs containing malicious content in the Computer field. An attacker can inject JavaScript into the Computer field of JSON logs that executes in the forensic examiner's browser session when viewing the generated HTML report, leading to information disclosure or code execution.
