AI-suggested
Upgrade OpenEMR to version 8.3.0 or later, where the vulnerability is fixed. No other mitigation is required as the fix addresses the root cause in the affected scripts.
Description
OpenEMR versions prior to 8.3.0 contain a stored cross-site scripting (XSS) vulnerability in two PHP form scripts. Authenticated clinical users can inject malicious event-handler markup by submitting crafted input containing double quotes, which escapes HTML attribute boundaries. This can lead to exposure of session data and protected health information or unauthorized patient-record actions when another clinician views the affected form. The vulnerability is fixed in OpenEMR version 8.3.0.
