CVE-2026-10624: SourceCodester HRM Employee Data Exposure Vulnerability

Technical summary

The vulnerability resides in /detailview.php of SourceCodester HRM 1.0 and is classified as improper control of resource identifiers (CWE-99). An authenticated attacker can craft requests with manipulated 'employeeid' values to retrieve employee records outside their authorized scope. The vulnerability requires valid login credentials but does not demand elevated privileges, and the attack surface is network-accessible. No user interaction is needed beyond the initial request.

Business impact

Unauthorized access to employee records poses confidentiality risks, potentially exposing sensitive personal and employment information. While the CVSS score reflects low to moderate severity, the reputational and compliance consequences—particularly under data protection regulations—may be significant. Organizations face potential notification obligations and increased insider threat vectors if employee data is exfiltrated by legitimate but malicious users.

Affected systems

SourceCodester Human Resource Management version 1.0 is confirmed affected. Organizations should audit their deployment inventory to identify all instances. The vulnerability applies to systems accessible over the network, regardless of internal or external exposure.

Exploitability

The attack is highly practical: it requires only valid login credentials and standard HTTP requests to manipulate the employeeid parameter. No complex exploitation techniques, race conditions, or client-side bypasses are necessary. Public disclosure of exploit code increases the likelihood of opportunistic attacks from both internal and external threat actors with valid credentials.

Remediation

Upgrade SourceCodester HRM to a patched version released after the vulnerability disclosure. Verify patch availability and compatibility with your deployment through the vendor's official advisory. In the interim, implement strong access controls and logging around the /detailview.php endpoint to detect suspicious employeeid parameter values.

Patch guidance

Contact SourceCodester or review their security advisory for confirmed patch versions addressing CVE-2026-10624. Apply patches in a controlled test environment before production rollout. Verify that access controls properly restrict employees to viewing only authorized records post-patch.

Detection guidance

Monitor access logs for /detailview.php requests where the employeeid parameter differs significantly from the authenticated user's own ID or department scope. Implement alerting for sequential or random employeeid parameter values that suggest enumeration attempts. Review user access to sensitive employee fields within your HRM system for anomalies.

Why prioritize this

Although the CVSS score is 4.3 (MEDIUM), the combination of public exploit availability, authenticated attack vector, and direct access to sensitive employee data warrants prompt remediation. Organizations should prioritize patching to reduce insider-threat risk and meet data protection compliance obligations.

Risk score, explained

CVSS 3.1 score of 4.3 reflects the moderate risk profile: network-accessible, requires authentication (lowering severity), and results in confidentiality loss without integrity or availability impact. The presence of disclosed exploits elevates operational risk despite the numerical score.
