node-multer: multer is a Node.js middleware for handling multipart/form-data uploads
CVE-2026-88932 is fixed in node-multer on 1 platform by DEBIAN-CVE-2026-88932 (version 2.4.0+~cs3.2.0-1), released September 14, 2026. It is not reported as exploited. Patch Radar priority: Routine.
multer is a Node.js middleware for handling multipart/form-data uploads. In versions 2.2.0 through 2.3.0, when a request using disk storage is aborted mid-upload, file writes that complete after multer has already run its abort cleanup are not removed, so each aborted upload can leave an orphaned file on disk. A remote unauthenticated attacker can repeatedly start and abort uploads to accumulate orphaned files and exhaust disk space, causing a denial of service. The issue is fixed in multer 2.4.0, and users should upgrade to 2.4.0 or later.
