OpenEMR before 8.5.0 contains a reflected cross-site scripting vulnerability in the Application module's auto-suggest endpoint, which echoes the searchMode POST parameter unencoded into a single-quoted onClick attribute. Attackers can induce an authenticated user to submit a single-quote payload to application/index/search, executing arbitrary JavaScript in that user's session to steal session cookies or disclose patient data.
