# CVE-2026-124463: OpenEMR before 8.3.0 Stored XSS via CAMOS Rx Print View

Status: published. Published: 2026-11-08. Updated: 2026-11-12.

OpenEMR before 8.3.0 contains a stored cross-site scripting vulnerability that allows authenticated users with CAMOS access to inject HTML by saving malicious CAMOS content through ajax_save.php. Attackers can store a script payload that executes unencoded when the entry is printed via the non-print_html branch of rx_print.php, performing actions and reading data as the victim user.
