Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
[email protected] 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 [email protected] or higher.
### Workarounds
None.
