Asymmetric denial of service - ReDoS In multer
Description
multer vulnerable to Denial of Service via file descriptor leak on aborted uploads
Impact
A vulnerability in multer 2.2.0 allows an attacker to trigger a Denial of Service (DoS) by aborting or truncating multipart uploads. When using diskStorage, the destination write stream is not closed if the upload is aborted before it finishes, so each failed request leaks an open file descriptor and retains its disk blocks until the process exits. Repeated failed uploads can exhaust the available file descriptors. All applications using multer's disk storage are affected.
Patches
Users should upgrade to 2.3.0.
Workarounds
None.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
