Hi, The following vulnerability was published for node-multiparty. CVE-2026-87908[0]: | multiparty is a Node.js library for parsing multipart/form-data | request bodies. In versions from 2.1.0 up to but not including | 4.3.1, the parser does not bound the amount of memory used while | accumulating the headers of a single multipart part. An | unauthenticated attacker can send a single request whose part | carries a very large volume of header bytes, forcing the parser to | buffer all of them and exhausting the process memory, which crashes | the server. This is a denial of service with no confidentiality or | integrity impact. The issue is fixed in multiparty 4.3.1, which caps | the size of the accumulated part headers. Users should upgrade to | multiparty 4.3.1 or later. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
