build(deps-dev): bump multer from 2.3.0 to 2.4.0 in /packages/http-client-java

[dependabot]

Bumps multer from 2.3.0 to 2.4.0.

Release notes

Sourced from multer's releases.

v2.4.0

Highlights

multer finally supports Google Cloud Functions and Firebase 🎉

These platforms read the request body before your code runs, so multer's classic req.pipe(busboy) received nothing: empty req.body, empty req.files, and nearly a decade of duplicated issues.

The new streamHandler option closes that gap: you decide how the body reaches the parser, so the pre-read rawBody just works (see image).

const multer = require('multer')
const upload = multer({
storage: multer.memoryStorage(),
streamHandler: (req, busboy) => {
// Cloud Functions / Firebase expose the pre-read body here
if (req.rawBody) busboy.end(req.rawBody)
else req.pipe(busboy)
}
})
app.post('/upload', upload.single('file'), (req, res) => {
res.json({ name: req.file.originalname, size: req.file.size })
})

This landed thanks to community PRs going back to 2017; their authors are credited as co-authors in the release.

Changelog

Sourced from multer's changelog.

2.4.0

• Fix CVE-2026-88932 (GHSA-3pph-fpjx-jg34)
• Add filename to LIMIT_FILE_SIZE and LIMIT_UNEXPECTED_FILE errors (#1416)
• Accept a function for limits, called with the request, to set limits per request (#1133)
• Add opt-in flush option to DiskStorage to fsync files before the callback runs (#1458)
• Expose busboy's defCharset, highWaterMark and fileHwm options (#1465)
• Add streamHandler option to feed busboy from pre-consumed bodies (Google Cloud Functions, Firebase) (#1466)
• Allow multer.diskStorage() to be called without options (#1471)
• Decode WHATWG-escaped characters (%0A, %0D, %22) in field names, matching file.originalname since 2.3.0: req.body keys, file.fieldname and err.field now carry the real name. If you matched the escaped spelling as a workaround, use the real name now (#1473)
• Report the decoded filename in err.filename on LIMIT_FILE_SIZE errors, matching file.originalname (#1478)
• Reject non-integer or negative limits values at construction time; a float limit silently disabled the check (#1395, #1335)
• Accept requests with exactly limits.parts parts; LIMIT_PART_COUNT now fires only when the limit is exceeded. If you set parts one higher to work around this, you can drop the extra one (#1446)
• Files skipped by fileFilter no longer count towards maxCount (#1426)
• Change the LIMIT_UNEXPECTED_FILE message to "Unexpected file field" (#426)
• Remove the concat-stream dependency (#1356)
• Docs: add JSDoc to the public API and document the storage engine stream contract (#1467, #1468)
• Docs: add FormData upload examples (#896)
• Docs: remove the translated READMEs (#1463)
• Internal: run the test suite on macOS (#1464)
