multiparty: Denial of Service via Prototype Pollution leads to Uncaught Exception
Impact
multiparty@4.2.3 and lower versions are vulnerable to denial of service via uncaught exception. By sending a multipart/form-data request with a field name that collides with an inherited Object.prototype property (e.g., __proto__, constructor, toString), the parser invokes .push() on the inherited prototype value rather than an array, throwing a TypeError that propagates as an uncaught exception and crashes the process. Any service accepting multipart uploads via multiparty is affected.
Patches
Users should upgrade to multiparty@4.3.0 or higher.
Workarounds
None.
