What is CVE-2026-124463?

OpenEMR versions prior to 8.3.0 are impacted by a stored cross-site scripting (XSS) vulnerability that affects users with CAMOS access. By exploiting this flaw, authenticated users can inject malicious HTML content through the ajax_save.php interface. This content may then be executed unescaped when rendered in the non-print_html context by rx_print.php, potentially allowing attackers to perform unauthorized actions and read sensitive data as the victim user.

Affected Version(s)
