Security readout for executives and security teams
Plain-English summary
CVE-2026-1146 is a cross-site scripting issue in Patients Waiting Area Queue Management System 1.0. A user with access can submit manipulated first or last name values through patient registration, potentially causing script content to run when another user views it. Public exploit disclosure is reported, but the provided sources do not show confirmed active exploitation.
Executive priority
Treat as a near-term remediation item if this application is used in patient-facing or operational workflows. Business risk is mainly session abuse, data integrity impact, or staff-targeted phishing through the application, not full system compromise based on current evidence.
Technical view
The vulnerability affects /php/api_register_patient.php in SourceCodester/Patrick Mvuma Patients Waiting Area Queue Management System 1.0. Manipulation of firstName or lastName can lead to XSS. CVSS v4.0 is 5.1 with network access, low complexity, low privileges required, and user interaction required. Sources list CWE-79 and CWE-94.
Likely exposure
Exposure is limited to organizations running version 1.0 of this specific queue management system, especially if reachable by staff or public users. Exploitation requires an authenticated or low-privileged context and a victim interaction, based on the CVSS vector.
Exploitation context
VulDB reports that an exploit has been publicly disclosed and may be used. The CVE is not listed as CISA KEV in the provided bundle, and no cited source confirms active exploitation in the wild.
Researcher notes
Sources identify XSS in firstName/lastName processing but do not provide a vendor patch status. Validate safely in a controlled environment without weaponized payloads. Prioritize determining whether the issue is reflected, stored, or both, and where encoded output is missing.
Mitigation direction
- Check SourceCodester or project maintainer guidance for an official fix or update.
- Restrict access to patient registration features to trusted users where feasible.
- Review custom code for proper encoding of firstName and lastName output.
- Apply web application filtering only as a temporary compensating control.
Validation and detection
- Inventory systems running Patients Waiting Area Queue Management System 1.0.
- Confirm whether /php/api_register_patient.php is present and accessible.
- Review handling of firstName and lastName for HTML/script encoding.
- Check logs for unusual patient-name entries containing markup-like content.

Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.
CWE-79: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
