CVE-2026-10624 Overview
CVE-2026-10624 is an Insecure Direct Object Reference (IDOR) vulnerability in SourceCodester Human Resource Management 1.0. The flaw resides in the /detailview.php script that powers the Employee View Page component. Attackers manipulate the employeeid parameter to access employee records that belong to other users. The issue is classified under CWE-99: Improper Control of Resource Identifiers. The exploit details have been disclosed publicly, and an authenticated remote attacker with low privileges can reach the vulnerable endpoint over the network.
Critical Impact
Authenticated users can enumerate the employeeid parameter on /detailview.php to view confidential HR records belonging to other employees, resulting in unauthorized disclosure of personal data.
Affected Products
- SourceCodester Human Resource Management 1.0
- Component: Employee View Page (/detailview.php)
- Parameter: employeeid

Technical Details for CVE-2026-10624
Vulnerability Analysis
The vulnerability is an Insecure Direct Object Reference in the /detailview.php endpoint. The application uses the user-supplied employeeid value as a direct reference to a database record without verifying that the requesting session owns or is authorized to view that record. Any authenticated user can substitute another employee's identifier and retrieve sensitive HR information. The weakness maps to CWE-99: Improper Control of Resource Identifiers. Disclosure on a public Medium blog lowers the barrier to exploitation.
Root Cause
The root cause is missing authorization on the resource identifier. The detailview.php handler trusts the inbound employeeid query parameter and queries the underlying record without enforcing an ownership or role check. Authorization should be evaluated server-side against the authenticated session before returning the employee object.
Attack Vector
Exploitation requires a valid low-privileged account and network access to the application. The attacker logs in, navigates to the Employee View Page, and increments or substitutes the employeeid value in the request URL. The server returns the targeted employee record without an access control check, enabling horizontal privilege escalation. No user interaction from the victim is required, and no special tooling beyond a browser or HTTP client is needed.
No verified exploit code is published. See the Medium blog and VulDB entry for technical write-ups.
Detection Methods for CVE-2026-10624
Indicators of Compromise
- Repeated GET requests to /detailview.php from a single session that iterate sequential employeeid values.
- Access patterns where one authenticated user retrieves records for many distinct employeeid parameters within a short window.
- Web server log entries showing 200 responses to /detailview.php?employeeid=<n> for identifiers not associated with the requesting account.
Detection Strategies
- Correlate the authenticated session identifier with the employeeid parameter at the application layer and alert on mismatches.
- Deploy a web application firewall rule that flags rapid enumeration of integer identifiers on /detailview.php.
- Review HR application audit logs for cross-account record views and unusual export or print actions.
Monitoring Recommendations
- Centralize web and application logs and retain them for forensic review of IDOR enumeration patterns.
- Baseline normal employeeid access counts per user and alert when thresholds are exceeded.
- Track outbound transfers from systems that view HR records to identify follow-on data exfiltration.
How to Mitigate CVE-2026-10624
Immediate Actions Required
- Restrict network access to the Human Resource Management 1.0 application to trusted networks until a fix is applied.
- Audit recent /detailview.php access logs for evidence of employeeid enumeration and notify affected employees if records were exposed.
- Rotate credentials for any low-privileged accounts that show abnormal access patterns.
Patch Information
No official vendor patch has been published for SourceCodester Human Resource Management 1.0 at the time of NVD publication. Monitor the SourceCodester project page and the VulDB advisory for updates. Operators should treat the deployment as unmaintained until a vendor response is confirmed.
Workarounds
- Add a server-side check in detailview.php that compares the session user against the owner or role permitted to view the requested employeeid.
- Replace sequential integer identifiers with unguessable values such as UUIDs to slow enumeration.
- Place the application behind an authenticating reverse proxy or VPN to limit exposure while a code fix is developed.
- Disable or remove the Employee View Page feature if it is not required for business operations.
