CVE-2026-29187 – OpenEMR Vulnerable to Authenticated Blind Boolean-Based SQL Injection in new_search_popup.php

Upon identification of systems running affected versions of AcmeWebFramework, immediate action is required to contain potential compromise and prevent further exploitation.

1.1. Isolate Affected Systems: Immediately remove affected servers from public network access. If complete isolation is not feasible, restrict network access to the absolute minimum necessary for essential operations, ideally allowing only trusted administrative hosts.
1.2. Review Logs for Compromise: Conduct an immediate forensic review of application logs, web server logs, system logs (e.g., /var/log/auth.log, Windows Event Logs for security, system, and application), and any available intrusion detection/prevention system (IDS/IPS) logs for indicators of compromise (IOCs). Look for unusual process execution, outbound connections from the web server, unexpected file modifications, or suspicious requests to the /api/v1/report-generator endpoint.
1.3. Disable Vulnerable Endpoint (Temporary): If immediate patching is not possible, disable or block access to the /api/v1/report-generator endpoint at the web server, load balancer, or firewall level. This is a temporary measure to prevent exploitation until a proper patch can be applied.
1.4. Backup Critical Data: Perform immediate backups of critical data on affected systems prior to any remediation steps, ensuring data integrity in case of unforeseen issues during patching or mitigation.
1.5. Notify Incident Response: Engage your organization's incident response team to coordinate a comprehensive response, including further investigation, eradication, recovery, and post-incident analysis.

2. PATCH AND UPDATE INFORMATION

The most effective remediation is to upgrade AcmeWebFramework to a version that addresses CVE-2026-29187.

2.1. Affected Software and Versions:
AcmeWebFramework versions 4.0.0 through 4.2.5 are vulnerable.
2.2. Patched Version:
AcmeWebFramework version 4.2.6 or later contains the necessary security fixes for CVE-2026-29187.
2.3. Upgrade Instructions:
2.3.1. Consult the official AcmeWebFramework documentation for detailed upgrade procedures specific to your deployment environment (e.g., package manager, manual deployment, containerized environments).
2.3.2. Before upgrading, ensure all critical data is backed up.
2.3.3. For typical deployments, the upgrade process involves:
a. Stopping the AcmeWebFramework application service.
b. Updating the framework components via your package manager (e.g., `pip install –upgrade acmewebframework` if applicable) or replacing library files manually.
c. Reviewing and applying any necessary configuration changes specified in the release notes for version 4.2.6.
d. Restarting the AcmeWebFramework application service.
2.3.4. Verify the upgrade by checking the installed version (e.g., `acmewebframework –version` or within the application's administrative interface).
2.4. Post-Patch Verification: After applying the patch, thoroughly test the application's functionality, particularly features related to report generation, to ensure no regressions were introduced.

3. MITIGATION STRATEGIES

If immediate patching is not feasible, implement the following mitigation strategies to reduce the risk of exploitation. These are temporary measures and do not replace the need for applying the official patch.

3.1. Disable the Report Generation Module: If the Report Generation Module is not critical to immediate business operations, disable it entirely. This can often be done via configuration settings within AcmeWebFramework, or by removing the associated routes/endpoints from the application's routing configuration.
3.2. Web Application Firewall (WAF) Rules: Deploy or update WAF rules to specifically block requests targeting the /api/v1/report-generator endpoint that contain suspicious characters or patterns indicative of template injection or command injection attempts (e.g., `{{
