CVE-2026-120822: MongoDB Server authorization bypass in applyOps

CVE-2026-120822 · Severity: medium · CVSS 6.7 · Published 2026-11-10

MongoDB Server has an authorization check bypass in its replication administrative command that allows authenticated users with backup/restore privileges to access and modify collections they shouldn't have permission to touch. An attacker could drop, modify, or rename collections belonging to other users or read data they are not authorized to access, compromising data security and the integrity of the database.

Technical details

The applyOps command omits a UUID-targeted authorization check when the oplogApplicationMode parameter is set to a non-default value (Secondary, InitialSync, or Recovering) by the client, allowing an authenticated user to bypass the check introduced in SERVER-130139. An attacker with cluster applyOps and useUUID privileges can specify a UUID resolving to a collection they lack rights on and perform unauthorized drop, collMod, dropIndexes, or renameCollection operations. The vulnerability affects all releases carrying the SERVER-130139 fix.

Affected products

MongoDB Server 7.0.40+, 8.0.29+, 8.3.8+, 9.0.0+
