CVE-2025-6709

Pre-Authentication Denial of Service Vulnerability in MongoDB Server's OIDC Authentication

State: Published
Severity: 7.5 High
Published: Jun 26, 2025
Updated: Jun 26, 2025
Reserved: Jun 26, 2025

Description

The MongoDB Server is susceptible to a denial of service vulnerability due to improper handling of specific date values in JSON input when using OIDC authentication. This can be reproduced using the mongo shell to send a malicious JSON payload leading to an invariant failure and server crash. This issue affects MongoDB Server v7.0 versions prior to 7.0.17 and MongoDB Server v8.0 versions prior to 8.0.5.

The same issue affects MongoDB Server v6.0 versions prior to 6.0.21, but an attacker can only induce denial of service after authenticating.
