CVE-2026-93532 Overview
CVE-2026-93532 is an improper authentication vulnerability [CWE-287] in the gedelumbung HospitalManagement application. The flaw resides in the Password Change Handler component, specifically in the simpan functions of application/modules/global/controllers/password.php and application/modules/global/controllers/profil.php. Attackers can manipulate the kode_user or username arguments to bypass authentication controls. The vulnerability is remotely exploitable and requires only low-level privileges. The affected codebase runs on a rolling release model, so no fixed version identifier exists. Public disclosure of the exploit has occurred, and the maintainer has not responded to the initial issue report.
Critical Impact
Authenticated attackers can change passwords for arbitrary accounts by manipulating user identifier parameters, enabling account takeover in a healthcare application.

Technical Details for CVE-2026-93532
Vulnerability Analysis
The vulnerability affects the password change and profile update workflows in gedelumbung HospitalManagement. The simpan (Indonesian for "save") functions accept a user identifier parameter, either kode_user or username, and use it to determine which account record to update. The handler fails to properly validate that the authenticated session owns the identifier submitted in the request. An attacker with any valid low-privilege account can therefore submit a request targeting another user's identifier and change that account's password. This chain enables full account takeover of higher-privileged accounts, including administrative users of the hospital management system.
Root Cause
The root cause is improper authentication [CWE-287] in the server-side handler. The code trusts the client-supplied kode_user or username value rather than binding the password change operation to the identifier of the currently authenticated session. This is a broken access control pattern where authorization is inferred from request parameters instead of the session context.
Attack Vector
Exploitation requires network access to the application and any valid user account. An attacker authenticates normally, then submits a crafted POST request to the password.php or profil.phpsimpan endpoint. The request substitutes another user's kode_user or username value along with a new password. The server processes the request without confirming ownership and rewrites the credentials of the targeted account. Because the exploit has been publicly disclosed and requires no specialized tooling, opportunistic exploitation is feasible.
No verified proof-of-concept code has been published beyond the referenced GitHub Issue #7 and the VulDB entry for CVE-2026-93532. Refer to those references for additional technical detail.

Stop Identity AttacksDetection Methods for CVE-2026-93532
Indicators of Compromise
- Unexpected password change events in application logs where the authenticated session identifier does not match the kode_user or username parameter in the request body.
- Successful logins to administrative or clinical accounts from source addresses not previously associated with those users.
- Multiple sequential POST requests to /application/modules/global/controllers/password.php or /profil.php from a single low-privilege session.
Detection Strategies
- Instrument the web server or reverse proxy to log the full POST body for the simpan endpoints and correlate against session ownership.
- Deploy a web application firewall rule that flags requests where the submitted kode_user/username parameter differs from the account identifier bound to the session cookie.
- Baseline normal password change frequency per account and alert on anomalies.
Monitoring Recommendations
- Forward application and web server access logs to a centralized analytics platform for correlation with authentication events.
- Enable alerting on password changes affecting administrative accounts outside of scheduled maintenance windows.
- Review database audit trails for UPDATE statements against user credential tables that originate from unexpected session contexts.
How to Mitigate CVE-2026-93532
Immediate Actions Required
- Restrict network exposure of the HospitalManagement application to trusted internal networks or a VPN until a fix is available.
- Audit all user accounts for unauthorized password changes and force a password reset across the user base.
- Implement a temporary WAF rule that blocks requests to the simpan endpoints when the kode_user or username parameter does not match the session-bound identifier.
Patch Information
The project operates on a rolling release model, and no vendor patch has been published at the time of NVD publication. According to the CVE record, the maintainer was notified through the GitHub issue tracker but has not responded. Organizations should monitor the gedelumbung/HospitalManagement repository for future commits addressing the simpan handlers.
Workarounds
- Modify the simpan functions in password.php and profil.php locally to derive the target user identifier from the server-side session rather than the request payload.
- Remove or comment out the profile update and password change routes if the functionality is not required for production use.
- Place the application behind an authenticating reverse proxy that enforces per-user path or parameter constraints.
