AI-suggested

  1. Immediate upgrade to horilla version 1.5.0 or later, which patches the vulnerability by properly neutralizing output and restricting file upload types.
  2. Implement strict server-side validation to restrict uploaded file types to safe image formats only (e.g., JPEG, PNG), explicitly blocking HTML or script files.
  3. Employ Content Security Policy (CSP) headers to limit execution of malicious scripts from uploaded content.
  4. Monitor file upload directories for suspicious files and regularly audit uploaded content.
  5. Enforce multi-factor authentication (MFA) to reduce risk from compromised credentials.
  6. Educate users about phishing risks, especially within internal applications, to reduce social engineering success.
  7. Review and tighten access controls to limit authenticated user privileges to the minimum necessary.
  8. Implement web application firewalls (WAF) with rules to detect and block malicious payloads in uploads.
  9. Conduct regular security assessments and penetration testing focused on file upload functionalities.
  10. Maintain incident response readiness to quickly address any detected exploitation attempts.

Description

CVE-2026-24010 is a high-severity file upload vulnerability in horilla versions prior to 1.5.0, an open-source Human Resource Management System. Authenticated attackers can upload malicious HTML files disguised as profile pictures, enabling phishing attacks by presenting fake login pages to users. This allows credential theft and potential account takeover without requiring user interaction beyond visiting the malicious URL. The vulnerability stems from improper neutralization of special elements in output used by downstream components (CWE-74). Although no known exploits are currently in the wild, the impact on confidentiality, integrity, and availability is high. The issue is patched in version 1.5.0.
