All the vulnerabilities related to the version 3.1.2 of the package
Prototype Pollution in immer
This affects the package immer before 9.0.6. A type confusion vulnerability can lead to a bypass of CVE-2020-28477 when the user-provided keys used in the path parameter are arrays. In particular, this bypass is possible because the condition (p === "__proto__" || p === "constructor")
in applyPatches_
returns false if p
is ['__proto__']
(or ['constructor']
). The ===
operator (strict equality operator) returns false if the operands have different type.
Prototype Pollution in immer
immer is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution').
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick
, set
, setWith
, update
, updateWith
, and zipObjectDeep
allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
