CVE-2025-66291: A Critical Vulnerability in OrangeHRM

The recent discovery of CVE-2025-66291 has raised significant concerns for system administrators and hosting providers using OrangeHRM. This vulnerability allows unauthorized users to access sensitive interview attachments, putting confidential information at risk. Effective server security is crucial in mitigating these types of threats.

Understanding the Vulnerability

From version 5.0 to 5.7, the interview attachment retrieval endpoint in the Recruitment module of OrangeHRM improperly authorizes requests. This means that an authenticated user can obtain files simply by having the correct session and identifiers without proper checks. Thus, users without access to the recruitment workflows can exploit this loophole, resulting in a significant breach of security.

Why It Matters for Server Admins

This vulnerability highlights a critical flaw that can lead to unauthorized access to sensitive data. System administrators and hosting providers must be vigilant because this type of breach can have wide-ranging consequences:

• Exposure of sensitive data, such as candidate evaluations and resumes.
• Potential legal implications if confidential information is compromised.
• Damage to reputation and trust with clients and candidates.

Mitigation Steps for Security

To safeguard your infrastructure, consider implementing the following practical steps:

• Update Software: Upgrade OrangeHRM to version 5.8 or later, which includes necessary patches for this vulnerability.
• Service Configuration: Ensure that your web application firewall (WAF) settings block unauthorized access attempts.
• Access Control Policies: Review and enforce strict access controls to sensitive data, ensuring only authorized personnel can retrieve specific attachments.
• Continuous Monitoring: Implement regular monitoring and malware detection systems to identify and respond to breaches or suspicious activities promptly.
