CVE-2025-6707 is an authorization vulnerability classified under CWE-863 (Incorrect Authorization) affecting MongoDB Server versions 5.0 prior to 5.0.31, 6.0 prior to 6.0.24, 7.0 prior to 7.0.21, and 8.0 prior to 8.0.5. The vulnerability arises when an authenticated user’s request executes with stale privileges following an intentional privilege change by an authorized administrator. This indicates that the MongoDB Server does not immediately enforce updated privilege changes, allowing users to retain elevated or prior permissions temporarily. The vulnerability requires the attacker to be authenticated with at least low privileges and does not require user interaction, but the attack complexity is high due to the need for specific timing and conditions. The CVSS v3.1 base score is 4.2 (medium), reflecting low confidentiality and integrity impact and no availability impact. The flaw could allow unauthorized data access or modification if exploited, undermining the principle of least privilege. No known exploits have been reported in the wild as of the publication date. The issue affects multiple major MongoDB versions, indicating a broad impact across deployments. MongoDB is widely used in enterprise, cloud, and web applications, making this vulnerability relevant to many organizations. The lack of immediate privilege enforcement could be exploited in environments where privilege changes are frequent or where administrators revoke access to mitigate insider threats or compromised accounts.

The primary impact of CVE-2025-6707 is the potential for unauthorized access or modification of data due to stale privilege enforcement. Organizations relying on MongoDB for critical applications may face confidentiality breaches if users retain access rights longer than intended. Integrity could also be compromised if users perform unauthorized operations during the window of stale privileges. Although availability is not affected, the risk to data security and compliance is significant, especially in regulated industries. Attackers with authenticated access could exploit this flaw to escalate privileges or bypass recently applied restrictions, increasing the risk of insider threats or lateral movement within networks. The vulnerability affects multiple major MongoDB versions, amplifying its reach globally. Organizations with dynamic user privilege management or frequent administrative changes are particularly vulnerable. Failure to patch could lead to data leaks, unauthorized data manipulation, and potential regulatory penalties.

Organizations should immediately upgrade MongoDB Server to the fixed versions: 5.0.31 or later, 6.0.24 or later, 7.0.21 or later, and 8.0.5 or later. Until patches are applied, administrators should minimize privilege changes during active user sessions and consider temporarily disabling non-essential user accounts. Implement monitoring to detect anomalous access patterns that could indicate exploitation attempts. Regularly audit user privileges and session states to ensure that revoked permissions are enforced promptly. Employ network segmentation and strict access controls to limit authenticated user exposure. Consider integrating MongoDB with external identity and access management (IAM) solutions that provide real-time privilege enforcement. Additionally, review and harden MongoDB authentication and authorization configurations to reduce the attack surface. Document and test incident response plans for potential misuse of stale privileges.
