CVE-2026-13061: CWE-863: Incorrect Authorization in MongoDB MongoDB Server
CVE-2026-13061 is a medium-severity vulnerability in MongoDB Server where an authenticated user can view session metadata of other users via the $listSessions aggregation stage. This metadata, normally restricted to cluster-level administrators, includes active session IDs, usernames, and activity timestamps. The vulnerability affects MongoDB Server versions 7.0, 8.0, and 8.3.0. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13061) involves incorrect authorization (CWE-863) in MongoDB Server. Authenticated users with limited privileges may access session metadata belonging to other users through the $listSessions aggregation stage. The exposed information includes active session identifiers, associated usernames, and timestamps of activity, which should only be accessible to users with cluster-level administrative privileges. The issue affects MongoDB Server versions 7.0, 8.0, and 8.3.0. No vendor advisory or patch is currently available, and no known exploitation has been reported.
Potential Impact
An authenticated user with limited privileges can view sensitive session metadata of other users, potentially aiding in reconnaissance or further attacks. The exposure includes active session IDs, usernames, and activity timestamps, which are normally restricted to cluster administrators. This could lead to privacy concerns and unauthorized insight into user activity but does not directly allow privilege escalation or remote code execution based on the available data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict authenticated user privileges to the minimum necessary and monitor access to the $listSessions aggregation stage. Avoid granting cluster-level administrative privileges broadly. Follow MongoDB's official channels for updates on patches or mitigations.
