Last modified

CVE-2026-24038 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the OTP handling logic has a flawed equality check that can be bypassed. EPSS estimates a 0.44% chance of exploitation in the next 30 days.

Description

Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the OTP handling logic has a flawed equality check that can be bypassed. When an OTP expires, the server returns None, and if an attacker omits the otp field from their POST request, the user-supplied OTP is also None, causing the comparison user_otp == otp to pass. This allows an attacker to bypass two-factor authentication entirely without ever providing a valid OTP. If administrative accounts are targeted, it could lead to compromise of sensitive HR data, manipulation of employee records, and further system-wide abuse. This issue has been fixed in version 1.5.0.
