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 Content-Disposition header whose filename* parameter contains a malformed percent-encoding, the parser invokes decodeURI on the value without try/catch. The resulting URIError propagates as an uncaught exception and crashes the process. Impact: any service accepting multipart uploads via multiparty is affected. Workarounds: none. Upgrade to multiparty@4.3.0 or higher.

GHSA-xh3c-6gcq-g4rv — multiparty vulnerable to Denial of Service via Uncaught Exception in filename* parameter parsing

Affected: npm: multiparty

### 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 `Content-Disposition: filename*=utf-8''` header containing a malformed percent-encoding (e.g., `%FF`, `%GG`), the parser invokes `decodeURI` on the value without try/catch. The resulting `URIError` 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.
