Overview
Affected versions of this package are vulnerable to Excessive Platform Resource Consumption within a Loop through repeated compilation of a loop-invariant regular expression inside the DecodeObject process. An attacker can exhaust CPU resources and degrade or deny service to legitimate users by sending requests with a large number of junk query keys, causing the server to perform excessive regular expression compilations proportional to the number of supplied keys.
