GHSA-pm2v-5p99-37p2: OpenEMR: Stored XSS via `text()` Misuse in Double-Quoted HTML Attribute

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/forms/transfersummary/new.php and interface/forms/functionalcognitivestatus/new.php render stored transferto, code, and codetext values with text(), which uses ENTNOQUOTES, inside double-quoted HTML value attributes. An authenticated clinical user can store a value containing a double quote that escapes the attribute and injects event-handler markup when another clinician opens the form. Successful exploitation can expose session data and protected health information or permit patient-record actions in the victim's session. This issue is fixed in version 8.3.0.
