Security readout for executives and security teams
Plain-English summary
CVE-2026-25743 is a stored cross-site scripting flaw in OpenEMR before 8.0.0. A logged-in user with the Forms administration role can save malicious questionnaire answers. When another user with that role views the encounter page or visit history, JavaScript may run in their browser. The vendor advisory says version 8.0.0 fixes it.
Executive priority
Prioritize remediation for healthcare environments using OpenEMR, particularly shared clinical administration systems. Although exploitation requires a privileged authenticated user, stored XSS can affect other privileged users and sensitive patient workflows. Upgrade planning should be prompt but can be risk-ranked below unauthenticated remote-code-execution issues.
Technical view
OpenEMR versions prior to 8.0.0 improperly display questionnaire answer content, enabling stored XSS. The issue requires authentication and the specific Forms administration role. Execution occurs when a similarly privileged user views stored form answers in patient encounter pages or visit history. CVSS 4.0 is 7.2, with high confidentiality and integrity impact noted.
Likely exposure
Organizations running OpenEMR below 8.0.0 are potentially exposed, especially where multiple users have the Forms administration role. Exposure is role-limited, but the affected workflow involves patient encounter and visit history views, which may contain sensitive clinical context.
Exploitation context
The source bundle does not indicate known active exploitation, and KEV is false. Exploitation requires an authenticated attacker with Forms administration privileges and a victim user with the same role viewing the stored answers. This limits broad internet-scale exploitation but remains important in healthcare environments with shared administrative workflows.
Researcher notes
Evidence is limited to the CVE record, GitHub advisory, and fixing commit. The advisory identifies stored XSS in questionnaire answer display and confirms OpenEMR 8.0.0 as the fixed version. No public source in the bundle claims exploitation in the wild or provides broader affected product information.
Mitigation direction
- Upgrade OpenEMR to version 8.0.0 or later.
- Review vendor advisory for any additional deployment-specific guidance.
- Limit Forms administration role membership to users who require it.
- Investigate suspicious questionnaire answers entered before upgrade.
Validation and detection
- Inventory OpenEMR instances and confirm installed version.
- Identify any OpenEMR systems running versions earlier than 8.0.0.
- Review role assignments for Forms administration privileges.
- Confirm the vendor security advisory applies to your deployment.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
