MongoDB mongos Improper Authorization Check in Cursor Termination Allowing Cross-Database Privilege Misuse (CVE-2026-13068)
Description
CVE-2026-13068 is a vulnerability in MongoDB mongos where an authenticated user with cursor termination privileges on one database can improperly terminate active cursors on another database.

Technical Analysis
This vulnerability arises from an improper authorization check in MongoDB mongos cursor termination functionality. Specifically, an authenticated user who has permission to terminate cursors on one database may be able to terminate cursors on a different database, violating intended privilege boundaries. This flaw can disrupt ongoing queries for other users by prematurely terminating their cursors. The issue is tracked as CVE-2026-13068 and affects multiple MongoDB versions prior to patched releases.
Potential Impact
The impact is limited to disruption of query operations on databases other than the one where the user holds cursor termination privileges. There is no indication of privilege escalation beyond cursor termination or data access. The vulnerability allows cross-database misuse of cursor termination privileges, potentially affecting availability of query results for other users.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade to fixed MongoDB versions to remediate the issue. The affected versions are prior to 7.0.39, 8.0.28, 8.2.12, and 8.3.7 respectively. Applying these official fixes will prevent improper cross-database cursor termination.
