CVE-2025-31511 is a security vulnerability identified in AlertEnterprise Guardian version 4.1.14.2.2.1. The vulnerability allows an attacker to bypass the manager approval process by manipulating the user ID parameter in the Request Building Access requestSubmit API call. Specifically, the system fails to properly validate or authenticate the user ID associated with access requests, enabling an attacker to impersonate or escalate privileges without requiring legitimate managerial consent. This flaw undermines the integrity of the access control mechanism within the AlertEnterprise Guardian platform, which is typically used for physical security and access management in enterprise environments. The lack of proper authorization checks in the API endpoint means that unauthorized users could potentially gain access to restricted physical locations or resources by submitting forged requests. Although there are no known exploits currently in the wild, the vulnerability poses a significant risk due to the critical nature of physical access control systems and the potential for insider threat or external attackers to exploit this weakness. No CVSS score has been assigned yet, and no patches or mitigations have been officially published as of the vulnerability disclosure date.

For European organizations, this vulnerability could have serious consequences, especially for those relying on AlertEnterprise Guardian for managing physical access to sensitive facilities such as data centers, government buildings, research labs, or critical infrastructure sites. Unauthorized bypass of manager approval could lead to unauthorized physical entry, theft of intellectual property, sabotage, or compromise of safety protocols. The breach of physical security controls may also facilitate subsequent cyber intrusions if attackers gain access to networked systems within secured premises. Additionally, organizations subject to strict regulatory requirements around physical security and data protection (e.g., GDPR, NIS Directive) could face compliance violations and reputational damage if this vulnerability is exploited. The absence of known exploits currently reduces immediate risk, but the potential impact remains high given the criticality of the affected system's function.

Given the lack of an official patch, European organizations using AlertEnterprise Guardian 4.1.14.2.2.1 should implement compensating controls immediately. These include: 1) Restricting API access to trusted networks and authenticated users only, employing network segmentation and firewall rules to limit exposure of the requestSubmit API endpoint. 2) Implementing additional monitoring and alerting on anomalous access requests, especially those that deviate from normal user behavior or originate from unexpected sources. 3) Enforcing multi-factor authentication and strong identity verification for all users submitting access requests to reduce the risk of impersonation. 4) Conducting manual verification of access requests where possible until a patch is available. 5) Engaging with AlertEnterprise support to obtain timelines for official fixes and applying updates promptly once released. 6) Reviewing and tightening physical security policies and procedures to detect and respond to unauthorized access attempts. These measures go beyond generic advice by focusing on network-level controls, behavioral monitoring, and procedural safeguards tailored to the specific API vulnerability.
