Overview
About vulnerability
Impact
A vulnerability in multer allows a remote, unauthenticated attacker to crash the Node.js process with a single multipart/form-data request. Two specially crafted text field names cause an uncaught RangeError: Invalid array length inside multer’s field parsing, which is not routed to the application error handler and terminates the process. All applications using multer to parse multipart requests are affected.
Patches
Users should upgrade to 2.3.0.
Workarounds
None.
