CVE-2025-66225 Overview
CVE-2025-66225 is a high-severity authentication flaw in OrangeHRM, a widely deployed human resource management (HRM) system. The vulnerability affects versions 5.0 through 5.7 and resides in the password reset workflow. The application fails to verify that the username submitted in the final reset request matches the account that originally initiated the reset. An attacker who can receive a valid reset link for any account they control can modify the username parameter to target a different user, including administrators. The flaw enables full account takeover and is tracked under [CWE-640: Weak Password Recovery Mechanism] and [CWE-20: Improper Input Validation]. OrangeHRM addressed the issue in version 5.8.
Critical Impact
Authenticated attackers with access to any reset email can hijack arbitrary accounts, including privileged administrator accounts, leading to full compromise of HR data.
Affected Products
- OrangeHRM version 5.0 through 5.7
- OrangeHRM Open Source edition deployments using the affected versions
- Self-hosted OrangeHRM instances exposing the password reset endpoint

Technical Details for CVE-2025-66225
Vulnerability Analysis
The vulnerability is a business logic flaw in the OrangeHRM password reset workflow. When a user initiates a reset, the application issues a token-bound reset link to the requester's email. The final step in the workflow accepts both the reset token and a username parameter from the submitted form. The server validates that the token is well-formed but does not bind the token to the original requesting account. An attacker can therefore complete a reset using a valid token issued to their own account while supplying the username of a target user. The server writes the new password to the account identified by the supplied username, granting the attacker control of that account.
Root Cause
The root cause is missing server-side correlation between the password reset token and the account that originated the reset. The application trusts the client-supplied username field at the final step rather than deriving the target account from the validated token. This pattern matches [CWE-640] and is compounded by insufficient input validation [CWE-20].
Attack Vector
The attack requires network access to the OrangeHRM web interface and the ability to receive a password reset email for any account the attacker legitimately controls. The attacker requests a password reset for their own account, retrieves the valid token from email, then submits the final reset request while substituting the username parameter with the target account, such as an HR administrator. No prior knowledge of the target's password is required.
No verified public exploit code is available. See the OrangeHRM GitHub Security Advisory GHSA-5ghw-9775-v263 for vendor technical details.
Detection Methods for CVE-2025-66225
Indicators of Compromise
- Password reset confirmation requests where the submitted username differs from the account that originally requested the reset token.
- Unexpected password changes for administrator or HR manager accounts followed by logins from new IP addresses or user agents.
- Multiple password reset initiations from a single low-privileged account in a short time window.
Detection Strategies
- Review web server and application logs for POST requests to the OrangeHRM password reset endpoint and correlate the username field with the account associated with the reset token.
- Alert on password changes for privileged OrangeHRM accounts that are not preceded by a reset email sent to that account's registered address.
- Inspect audit trails for sequential reset-initiation and reset-completion events that reference different usernames.
Monitoring Recommendations
- Forward OrangeHRM application logs and authentication events to a centralized logging or SIEM platform for continuous review.
- Monitor administrative login events for anomalous source IPs, geolocations, or session times following password reset activity.
- Track failed and successful login rates per account to identify takeover attempts after a reset.
How to Mitigate CVE-2025-66225
Immediate Actions Required
- Upgrade OrangeHRM to version 5.8 or later, which enforces binding between the reset token and the originating account.
- Audit recent password reset activity in versions 5.0 through 5.7 and force password resets for any accounts with suspicious reset events.
- Restrict network exposure of the OrangeHRM web interface to trusted networks or behind a VPN until patching is complete.
Patch Information
OrangeHRM has released a fix in version 5.8. The patch ensures the final password reset request validates that the supplied username matches the account associated with the issued reset token. Refer to the OrangeHRM GitHub Security Advisory GHSA-5ghw-9775-v263 for release notes and upgrade instructions.
Workarounds
- Temporarily disable the self-service password reset feature and require administrator-mediated password resets until version 5.8 is deployed.
- Place the OrangeHRM application behind a web application firewall (WAF) and block reset requests where the submitted username does not match the account tied to the reset token session.
- Enforce multi-factor authentication (MFA) on all administrator and HR accounts to reduce the impact of password takeover.
