Vulnerability	Vulnerable Version
H Allocation of Resources Without Limits or Throttling multiparty is a multipart/form-data parser which supports streaming Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in its part header handling, which bounds accumulated field values and file sizes but places no limit on the size of an individual part's headers. An attacker can exhaust server memory and crash the process with a single request by sending a multipart/form-data body whose part header never terminates. This requires only that the service accept multipart uploads through this parser, and the documented field and file size limits do not constrain the header accumulation. How to fix Allocation of Resources Without Limits or Throttling? Upgrade `multiparty` to version 4.3.1 or higher.	>=2.1.0 <4.3.1
H Regular Expression Denial of Service (ReDoS) multiparty is a multipart/form-data parser which supports streaming Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the `Content-Disposition` filename parameter parsing. An attacker can cause excessive resource consumption and block the event loop by submitting a multipart upload with a specially crafted long header value that triggers regular expression backtracking. How to fix Regular Expression Denial of Service (ReDoS)? Upgrade `multiparty` to version 4.3.0 or higher.	<4.3.0
H Uncaught Exception multiparty is a multipart/form-data parser which supports streaming Affected versions of this package are vulnerable to Uncaught Exception through the parsing of `multipart/form-data` requests containing field names that collide with inherited `Object.prototype` properties. An attacker can cause the process to crash by sending specially crafted requests that trigger an uncaught exception. How to fix Uncaught Exception? Upgrade `multiparty` to version 4.3.0 or higher.	<4.3.0
H Improper Handling of Exceptional Conditions multiparty is a multipart/form-data parser which supports streaming Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the `filename` parameter parsing in multipart form-data requests. An attacker can cause the process to crash by sending a request with a malformed percent-encoding in the `filename` parameter, which triggers an uncaught exception. How to fix Improper Handling of Exceptional Conditions? Upgrade `multiparty` to version 4.3.0 or higher.	<4.3.0

Allocation of Resources Without Limits or Throttling

multiparty is a multipart/form-data parser which supports streaming

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in its part header handling, which bounds accumulated field values and file sizes but places no limit on the size of an individual part's headers. An attacker can exhaust server memory and crash the process with a single request by sending a multipart/form-data body whose part header never terminates. This requires only that the service accept multipart uploads through this parser, and the documented field and file size limits do not constrain the header accumulation.

How to fix Allocation of Resources Without Limits or Throttling?

Upgrade multiparty to version 4.3.1 or higher.

Regular Expression Denial of Service (ReDoS)

multiparty is a multipart/form-data parser which supports streaming

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the Content-Disposition filename parameter parsing. An attacker can cause excessive resource consumption and block the event loop by submitting a multipart upload with a specially crafted long header value that triggers regular expression backtracking.

How to fix Regular Expression Denial of Service (ReDoS)?

Upgrade multiparty to version 4.3.0 or higher.

<4.3.0

Uncaught Exception

multiparty is a multipart/form-data parser which supports streaming

Affected versions of this package are vulnerable to Uncaught Exception through the parsing of multipart/form-data requests containing field names that collide with inherited Object.prototype properties. An attacker can cause the process to crash by sending specially crafted requests that trigger an uncaught exception.

How to fix Uncaught Exception?

Upgrade multiparty to version 4.3.0 or higher.

<4.3.0

Improper Handling of Exceptional Conditions

multiparty is a multipart/form-data parser which supports streaming

Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the filename* parameter parsing in multipart form-data requests. An attacker can cause the process to crash by sending a request with a malformed percent-encoding in the filename* parameter, which triggers an uncaught exception.

How to fix Improper Handling of Exceptional Conditions?

Upgrade multiparty to version 4.3.0 or higher.
