CyberRota Analysis
AI-GeneratedThe Countly Server DBViewer in MongoDB is vulnerable to an authorization bypass due to improper handling of user-controlled aggregation JSON, allowing non-admin users to inject forbidden operators into sub-pipelines. This flaw can lead to unauthorized access to sensitive data, including password-reset tokens, potentially enabling account takeover. Organizations using MongoDB with Countly Server should prioritize addressing this vulnerability to safeguard against data breaches and unauthorized access.

Original NVD Description
An authorization bypass vulnerability exists in the Countly Server DBViewer due to flawed sub-pipeline detection in the aggregation stage sanitizer. The /o/db aggregation endpoint parses user-controlled aggregation JSON and passes it through a stage sanitizer that determines whether a nested array is a sub-pipeline by checking if every element contains a key present in a hardcoded KNOWN_STAGE_OPERATORS set. If any element contains an unrecognized stage key, such as the undocumented MongoDB-internal $_internalInhibitOptimization, the sanitizer misclassifies the entire branch as a generic array and skips stage-level stripping for all sibling stages. This allows a non-admin user with DBViewer read permission to inject forbidden operators like $lookup inside $facet sub-pipelines, performing cross-collection joins into restricted collections. This leads to unauthorized read access to sensitive data including password-reset tokens (prid), enabling account takeover.
