CVE-2026-13059: CWE-807: Reliance on Untrusted Inputs in a Security Decision in MongoDB MongoDB Server
An authenticated user with low privileges may be able to perform unauthorized reads and writes on data protected by role-based query-level access controls, due to insufficient validation of certain client-supplied command parameters. The issue affects find, update, delete, and aggregate commands in non-apiStrict configurations.
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of client-supplied command parameters in MongoDB Server, allowing authenticated users with low privileges to bypass role-based query-level access controls. The affected commands include find, update, delete, and aggregate when the server is configured without apiStrict mode. This could lead to unauthorized data reads and writes. The CVSS 4.0 base score is 8.6, indicating high severity. No official patch or remediation level has been provided as of the published date.
Potential Impact
An attacker with valid low-privilege authentication can exploit this vulnerability to access or modify data beyond their authorized scope, violating data confidentiality and integrity. This undermines the role-based access control mechanisms intended to protect sensitive data within MongoDB Server.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider enabling apiStrict mode if feasible, as the vulnerability affects non-apiStrict configurations. Review and restrict user privileges carefully to minimize potential exploitation.
