CVE-2026-78144: Barangay Resident Profiling Auth Bypass

CVE-2026-78144 is an authorization bypass flaw in Barangay Resident Profiling Management System 1.0 affecting the Boarder Management Module. Attackers can manipulate the ID parameter to bypass authorization checks. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2026-78144 Overview

CVE-2026-78144 is an authorization bypass vulnerability in code-projects Barangay Resident Profiling Management System 1.0. The flaw resides in the /boarders.php file within the Boarder Management Module. Attackers can manipulate the ID argument to bypass authorization controls and access records they should not view or modify. The attack executes remotely over the network and requires low-level privileges. A proof-of-concept exploit is publicly available, increasing the likelihood of opportunistic abuse against exposed deployments.

Critical Impact
Authenticated attackers can bypass authorization checks on the Boarder Management Module to access or manipulate resident records belonging to other users, compromising the confidentiality and integrity of profiled resident data.

Technical Details for CVE-2026-78144

Vulnerability Analysis

The vulnerability is classified under CWE-285: Improper Authorization. The /boarders.php endpoint accepts an ID parameter that references records in the Boarder Management Module. The application fails to verify whether the authenticated session owns or has permission to act on the referenced record. This produces an Insecure Direct Object Reference condition. An attacker with any valid low-privilege account can iterate the ID parameter to access records tied to other residents or administrators.

Root Cause

The root cause is a missing server-side authorization check between authentication and data access. The endpoint appears to trust the ID parameter without cross-referencing it against the session's permission scope. Access control decisions are effectively delegated to the client, which any attacker can manipulate through direct HTTP requests.

Attack Vector

The attack is remote and network-based. An attacker authenticates with any low-privilege account and issues crafted HTTP requests to /boarders.php with modified ID values. No user interaction is required. The publicly available proof-of-concept published as a GitHub Gist PoC demonstrates parameter tampering against the endpoint. Technical breakdowns are also documented in the VulDB Vulnerability Details entry.

No verified code examples are available. Refer to the linked advisories for request-level details of the authorization bypass.

Detection Methods for CVE-2026-78144

Indicators of Compromise

Sequential or non-sequential enumeration of the ID parameter in HTTP requests to /boarders.php from a single session.
Access to boarder or resident records by user accounts that have no legitimate business relationship to those records.
Unexpected HTTP 200 responses to /boarders.php?ID= requests from low-privilege sessions across a wide range of record identifiers.

Detection Strategies

Deploy web application firewall rules that flag rapid variation of the ID parameter on /boarders.php within a single session.
Correlate authentication logs with record-access logs to identify users touching records outside their assigned scope.
Implement per-user access baselining and alert when a session enumerates more records than a legitimate workflow would require.

Monitoring Recommendations

Enable verbose HTTP access logging on the PHP application server, including query strings and authenticated user identifiers.
Retain database query logs to trace which sessions read or wrote boarder records after authorization bypass attempts.
Monitor for anomalous outbound data volumes that could indicate bulk enumeration of resident profiles.

How to Mitigate CVE-2026-78144

Immediate Actions Required

Restrict network exposure of the Barangay Resident Profiling Management System 1.0 to trusted networks or place it behind a VPN.
Audit application logs for prior enumeration of /boarders.php?ID= values across all authenticated sessions.
Rotate credentials for accounts that show evidence of authorization bypass activity.

Patch Information

No vendor patch has been referenced in the advisory sources. Users should monitor the Code Projects Resource and the VulDB CVE-2026-78144 entry for updates. Until a fix is published, apply the workarounds below and consider retiring the affected version.

Workarounds

Add a server-side authorization check in /boarders.php that validates the authenticated session's ownership or role before returning record data.
Replace direct integer identifiers with unguessable, session-scoped tokens (indirect object references) for boarder records.
Enforce role-based access control at the database layer using views or row-level security so unauthorized queries return no data.
Deploy a web application firewall rule to block requests to /boarders.php where the ID parameter does not match a value previously issued to that session.
