loader-utils is vulnerable to Regular Expression Denial of Service (ReDoS) via url variable
A Regular expression denial of service (ReDoS) flaw was found in Function interpolateName in interpolateName.js in webpack loader-utils 2.0.0 via the url variable in interpolateName.js. A badly or maliciously formed string could be used to send crafted requests that cause a system to crash or take a disproportional amount of time to process. This issue has been patched in versions 1.4.2, 2.0.4 and 3.2.1.
Prototype pollution in webpack loader-utils
Prototype pollution vulnerability in function parseQuery in parseQuery.js in webpack loader-utils prior to version 2.0.3 via the name variable in parseQuery.js.
loader-utils is vulnerable to Regular Expression Denial of Service (ReDoS)
A regular expression denial of service (ReDoS) flaw was found in Function interpolateName in interpolateName.js in webpack loader-utils via the resourcePath variable in interpolateName.js. A badly or maliciously formed string could be used to send crafted requests that cause a system to crash or take a disproportional amount of time to process. This issue has been patched in versions 1.4.2, 2.0.4 and 3.2.1.
Prototype Pollution in object-path
object-path is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'). The del()
function fails to validate which Object properties it deletes. This allows attackers to modify the prototype of Object, causing the modification of default properties like toString
on all objects.
Prototype pollution in object-path
A prototype pollution vulnerability has been found in object-path
<= 0.11.4 affecting the set()
method. The vulnerability is limited to the includeInheritedProps
mode (if version >= 0.11.0 is used), which has to be explicitly enabled by creating a new instance of object-path
and setting the option includeInheritedProps: true
, or by using the default withInheritedProps
instance. The default operating mode is not affected by the vulnerability if version >= 0.11.0 is used. Any usage of set()
in versions < 0.11.0 is vulnerable.
Upgrade to version >= 0.11.5
Don't use the includeInheritedProps: true
options or the withInheritedProps
instance if using a version >= 0.11.0.

Prototype Pollution in object-path
This affects the package object-path before 0.11.6. A type confusion vulnerability can lead to a bypass of CVE-2020-15256 when the path components used in the path parameter are arrays. In particular, the condition currentPath === '__proto__'
returns false if currentPath
is ['__proto__']
. This is because the ===
operator returns always false when the type of the operands is different.
