6DescriptionGitHub Advisory
Horilla is a free and open source Human Resource Management System (HRMS). In 1.5.0, an insecure direct object reference in the employee document upload endpoint allows any authenticated user to overwrite or replace or corrupt another employee’s document by changing the document ID in the upload request. This enables unauthorized modification of HR records.
AnalysisAI
Authenticated users in Horilla HRMS 1.5.0 can overwrite or corrupt any employee's documents via insecure direct object reference (IDOR) in the document upload endpoint. By manipulating the document ID parameter in upload requests, attackers with low-level access can modify HR records belonging to other employees, including executives or administrators. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated access to Horilla HRMS as any valid employee user - no administrative privileges needed (CVSS PR:L confirms low-privilege access suffices). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents significant real-world risk despite no confirmed exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An HR assistant with basic Horilla access logs into the system using legitimate credentials. While uploading a personal document, they intercept the HTTP POST request and observe the document_id parameter set to their own document ID (e.g., doc_id=1234). … |
| Remediation | Upgrade Horilla HRMS from version 1.5.0 to the patched release version identified in the GitHub Security Advisory at https://github.com/horilla/horilla-hr/security/advisories/GHSA-q2qh-v828-r4p7 (specific patched version number not provided in available data - consult advisory directly). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Disable or restrict access to the document upload endpoint in Horilla HRMS 1.5.0 until patched; audit all document modifications in the past 30 days for unauthorized changes. …
