Vulnerability Details

A Denial of Service vulnerability exists in qs up to 6.8.0 due to insufficient sanitization of property in the gs.parse function. The merge() function allows the assignment of properties on an array in the query. For any property being assigned, a value in the array is converted to an object containing these properties. Essentially, this means that the property whose expected type is Array always has to be checked with Array.isArray() by the user. This may not be obvious to the user and can cause unexpected behavior.
WhiteSource Note: After conducting further research, WhiteSource has determined that versions 0.0.1--6.10.3 of qs are vulnerable to CVE-2021-44907.
