Title
Use-After-Free in MongoDB $graphLookup Aggregation Stage Leads to Denial of Service and Potential Remote Code Execution
Summary
An issue in MongoDB Server's $graphLookup aggregation stage could allow an authenticated user able to issue aggregation and memory-management commands to cause an internal reference to be used after the underlying memory has been freed. This could result in a server crash or, potentially, execution of unintended code.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
