This vulnerability has been fixed in MongoDB Server versions 7.0.48, 8.0.37, 8.3.16, and 9.0.7. Users should upgrade to these or later versions to remediate the issue. No additional mitigations are indicated by the vendor advisory.

Description

CVE-2026-120822 is an incorrect authorization vulnerability in MongoDB Server affecting versions 7.0.0 through 7.0.47, 8.0.0 through 8.0.36, 8.3.0 through 8.3.15, and 9.0.0 through 9.0.6. The flaw arises because the server may skip an authorization check on the resource targeted by a replication-related administrative command, relying on a client-supplied value. This allows users with backup and restore privileges to access and modify collections beyond their authorized scope, potentially leading to unauthorized data access and unintended changes to the collection catalog. The issue has been fixed in versions 7.0.48, 8.0.37, 8.3.16, and 9.0.7.
