CVE-2025-66289: OrangeHRM is a comprehensive human resource management (HRM) system. From version 5.0 to 5.7, the application does not invalidate existing sessions when a user is disabled or when a password change occurs, allowing active session cookies to remain valid indefinitely. As a result, a disabled user, or an attacker using a compromised account, can continue to access protected pages and perform operations as long as a prior session remains active. Because the server performs no session revocation or session-store cleanup during these critical state changes, disabling an account or updating credentials has no effect on already-established sessions. This makes administrative disable actions ineffective and allows unauthorized users to retain full access even after an account is closed or a password is reset, exposing the system to prolonged unauthorized use and significantly increasing the impact of account takeover scenarios. This issue has been patched in version 5.8.
The exploitability of CVE-2025-66289 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2025-66289 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-66289, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-66289, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
