Published Mar 31, 2022 · Updated Jul 9, 2026

Stored XSS in Chikitsa Patient Management Software 2.0.2 allows remote authenticated users to execute JavaScript in another user's browser. The patient insertion and four reporting pages render the first_name parameter without neutralizing script-capable HTML. A highly privileged account must submit the payload, and another user must open an affected page; exploitation can read or alter browser-accessible data.
