Technical details
A stored XSS vulnerability in OpenEMR's CAMOS encounter form and Rx print functionality: the ajax_save.php route stores user-supplied HTML content without encoding, and the rx_print.php route renders it unescaped in the non-print_html branch. An authenticated attacker with CAMOS form access can inject JavaScript that executes in the victim's browser session when they print the CAMOS entry, enabling session hijacking and unauthorized data access.
