CWE-863

Description

An issue in MongoDB Server's applyOps command could allow an authenticated user with specific non-default privileges to perform certain data-definition operations, such as dropping or modifying collections, against collections they do not have permission to manipulate. This is due to an inconsistency in how the target collection is determined between the authorization check and the actual operation.

Affected configurations

• mongodb mongodb (>= 7.0.0 < 7.0.40) • mongodb mongodb (>= 8.0.0 < 8.0.29) • mongodb mongodb (>= 8.2.0 <= 8.2.12) • mongodb mongodb (>= 8.3.0 < 8.3.8) • mongodb mongodb 9.0.0 • mongodb mongodb 9.1.0
