CVE-2021-42581 Information

Description

DISPUTED Prototype poisoning in function mapObjIndexed in Ramda 0.27.0 and earlier allows attackers to compromise integrity or availability of application via supplying a crafted object (that contains an own property _proto_) as an argument to the function. NOTE: the vendor disputes this because the observed behavior only means that a user can create objects that the user didn’t know would contain custom prototypes.
