CVE-2026-78142 Overview
CVE-2026-78142 is an authorization bypass vulnerability in code-projects Barangay Resident Profiling Management System 1.0. The flaw resides in the /archived_records.php file within the Restore/Delete component. Attackers manipulate the resident_id parameter to perform restore or delete operations without proper authorization checks [CWE-285]. The issue is remotely exploitable over the network and requires only low-privileged authentication. A public exploit has been disclosed, increasing the likelihood of opportunistic abuse against exposed deployments.
Critical Impact
Authenticated remote attackers can bypass authorization controls to restore or delete archived resident records, compromising the integrity and availability of resident profile data.
Affected Products
- code-projects Barangay Resident Profiling Management System 1.0
- Component: /archived_records.php Restore/Delete functionality

Technical Details for CVE-2026-78142
Vulnerability Analysis
The vulnerability affects the archived records handler at /archived_records.php, which exposes restore and delete actions in the Barangay Resident Profiling Management System. The application accepts a resident_id argument from the request without verifying whether the authenticated user is authorized to act on that specific record. This authorization gap allows any low-privileged user to modify records that belong to other users or scopes. The weakness maps to CWE-285 (Improper Authorization). Public proof-of-concept material has been released, and the EPSS probability stands at 0.22%, placing exploitation likelihood in the lower percentile range.
Root Cause
The root cause is missing authorization enforcement on server-side actions triggered through /archived_records.php. The application trusts client-supplied resident_id values and executes restore or delete operations without checking session ownership, role permissions, or record-level access control. This is a classic broken access control pattern where authentication is present but authorization is not enforced per resource.
Attack Vector
An authenticated attacker sends a crafted HTTP request to /archived_records.php supplying a resident_id value that references records outside the attacker's authorized scope. Because the endpoint does not validate ownership, the server performs the requested restore or delete action. The attack requires network access and low privileges, with no user interaction on the victim side.

Detection Methods for CVE-2026-78142
Indicators of Compromise
- Unexpected HTTP requests to /archived_records.php containing resident_id values that do not correlate with the authenticated session user.
- Archived resident records restored or deleted outside normal administrative workflows or business hours.
- Repeated sequential enumeration of resident_id values from a single authenticated session.
Detection Strategies
- Deploy web server access log analysis rules that flag requests to /archived_records.php where the acting user role is not administrative.
- Correlate application audit logs of restore and delete events with the authenticated user identity to detect cross-user record manipulation.
- Instrument the application to log denied and permitted authorization decisions for later analysis in a centralized logging platform.
Monitoring Recommendations
- Forward web and application logs to a centralized SIEM or data lake for correlation and long-term retention.
- Alert on bursts of restore or delete actions originating from a single IP address, session, or user account.
- Baseline normal administrative activity against /archived_records.php and alert on deviations in volume or timing.
How to Mitigate CVE-2026-78142
Immediate Actions Required
- Restrict network access to the Barangay Resident Profiling Management System until a fix is applied, limiting exposure to trusted internal networks only.
- Audit archived resident records for unauthorized restore or delete activity and restore known-good state from backups if tampering is confirmed.
- Rotate credentials for low-privileged accounts that may have been leveraged to trigger the vulnerable endpoint.
Patch Information
No vendor patch is referenced in the enriched CVE data at the time of publication. Monitor Code Projects Security Resources and the VulDB Vulnerability #394525 tracker for vendor updates and remediation guidance.
Workarounds
- Add server-side authorization checks in /archived_records.php that validate the authenticated user's permission to act on the supplied resident_id before performing restore or delete operations.
- Enforce role-based access control (RBAC) so that only administrative accounts can invoke restore and delete actions on archived records.
- Deploy a web application firewall (WAF) rule to block or challenge requests to /archived_records.php from non-administrative user sessions.
- Enable detailed application logging for every restore and delete action, including the requesting user, source IP, and target resident_id.
