Severity
  • 7.1 (High) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N CVSS Calculator
Summary
Post-auth null pointer dereference when aggregating against a view with empty search pipeline
Details

An authenticated user can crash mongod when running $rankFusion or $scoreFusion with an empty pipeline on a view.

When resolving a view, the server inspects the aggregation pipeline to determine whether it begins with an Atlas Search stage. For $rankFusion and $scoreFusion, this inspection reads the first element on each stage’s input pipeline array without first verifying that the array is non-empty. Supplying an empty pipeline causes a null pointer dereference and crashes the server.

This issue affects MongoDB Server 8.2 versions prior to 8.2.7.
