CVE-2026-8063: CWE-476: NULL Pointer Dereference in MongoDB Inc. MongoDB Server
CVE-2026-8063 is a high-severity vulnerability in MongoDB Server 8. 2. 0 where an authenticated user can cause a server crash by triggering a null pointer dereference. This occurs when running $rankFusion or $scoreFusion with an empty pipeline on a view, due to improper validation of the pipeline array before accessing its first element. The issue affects versions prior to 8. 2. 7 and leads to a denial of service via server crash.
AI Analysis
Technical Summary
This vulnerability arises because MongoDB Server 8.2.0 does not verify that the input pipeline array is non-empty before accessing its first element during the resolution of views involving $rankFusion or $scoreFusion aggregation stages. An authenticated user supplying an empty pipeline can cause a null pointer dereference, resulting in a server crash. The problem affects MongoDB Server versions 8.2.0 up to but not including 8.2.7.
Potential Impact
An authenticated user can cause a denial of service by crashing the mongod process, leading to service disruption. There is no indication of data corruption or unauthorized data access from the provided information. The impact is limited to availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions prior to 8.2.7, upgrading to version 8.2.7 or later is likely the intended fix once available. Until then, restrict access to trusted authenticated users to reduce risk.
