Description

[REJECTED CVE] A Denial of Service (DoS) vulnerability was identified in QS due to insufficient sanitization of properties in the gs.parse function. The merge() function allows assigning properties to an array in a query, which could unexpectedly convert array values into objects. If the expected type is an array, and it's not checked with Array.isArray(), it can lead to unexpected behavior. An attacker could exploit this by manipulating query inputs, causing the application to crash or behave incorrectly.
