Bumps [multer](https://github.com/expressjs/multer) from 2.2.0 to 2.4.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/expressjs/multer/releases">multer's releases</a>.</em></p> <blockquote> <h2>v2.4.0</h2> <h2>Highlights</h2> <p><strong>multer finally supports Google Cloud Functions and Firebase 🎉</strong></p> <p>These platforms read the request body before your code runs, so multer's classic <code>req.pipe(busboy)</code> received nothing: empty <code>req.body</code>, empty <code>req.files</code>, and nearly a decade of duplicated issues.</p> <p>The new <code>streamHandler</code> option closes that gap: you decide how the body reaches the parser, so the pre-read <code>rawBody</code> just works (see image).</p> <pre lang="js"><code>const multer = require('multer') <p>const upload = multer({<br /> storage: multer.memoryStorage(),<br /> streamHandler: (req, busboy) => {<br /> // Cloud Functions / Firebase expose the pre-read body here<br /> if (req.rawBody) busboy.end(req.rawBody)<br /> else req.pipe(busboy)<br /> }<br /> })</p> <p>app.post('/upload', upload.single('file'), (req, res) => {<br /> res.json({ name: req.file.originalname, size: req.file.size })<br /> })<br /> </code></pre></p> <p>This landed thanks to community PRs going back to 2017; their authors are credited as co-authors in the release.</p> <h2>Important: Security</h2> <ul> <li>Fix <a href="https://www.cve.org/CVERecord?id=CVE-2026-88932">CVE-2026-88932</a> (<a href="https://github.com/expressjs/multer/security/advisories/GHSA-3pph-fpjx-jg34">GHSA-3pph-fpjx-jg34</a>)</li> </ul> <h2>What's Changed</h2> <ul> <li>docs: remove README translations by <a href="https://github.com/UlisesGascon"><code>@UlisesGascon</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1463">expressjs/multer#1463</a></li> <li>ci: add macOS to the test matrix by <a href="https://github.com/kilisamemarisaaa"><code>@kilisamemarisaaa</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1464">expressjs/multer#1464</a></li> <li>feat. improve wording for LIMIT_UNEXPECTED_FILE error code by <a href="https://github.com/flashbag"><code>@flashbag</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/426">expressjs/multer#426</a></li> <li>feat: add filename to file errors by <a href="https://github.com/UjjwalKumar239"><code>@UjjwalKumar239</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1416">expressjs/multer#1416</a></li> <li>refactor: remove concat-stream dependency by <a href="https://github.com/Phillip9587"><code>@Phillip9587</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1356">expressjs/multer#1356</a></li> <li>fix: reject non-integer fileSize limits by <a href="https://github.com/abhu85"><code>@abhu85</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1395">expressjs/multer#1395</a></li> <li>fix: allow exactly limits.parts parts by <a href="https://github.com/deepakganesh78"><code>@deepakganesh78</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1446">expressjs/multer#1446</a></li> <li>fix: do not consume maxCount for files skipped by fileFilter by <a href="https://github.com/Sagargupta16"><code>@Sagargupta16</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1426">expressjs/multer#1426</a></li> <li>fix: validate all limits at construction time by <a href="https://github.com/ShubhamOulkar"><code>@ShubhamOulkar</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1335">expressjs/multer#1335</a></li> <li>test: cover storage engine _removeFile invocation semantics by <a href="https://github.com/kilisamemarisaaa"><code>@kilisamemarisaaa</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1460">expressjs/multer#1460</a></li> <li>feat: accept a function for limits by <a href="https://github.com/hossein-zare"><code>@hossein-zare</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1133">expressjs/multer#1133</a></li> <li>fix: add flush option to disk storage to fsync files before completion by <a href="https://github.com/kilisamemarisaaa"><code>@kilisamemarisaaa</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1458">expressjs/multer#1458</a></li> <li>feat: expose busboy defCharset, highWaterMark and fileHwm options by <a href="https://github.com/UlisesGascon"><code>@UlisesGascon</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1465">expressjs/multer#1465</a></li> <li>docs: describe the file stream contract for storage engines by <a href="https://github.com/UlisesGascon"><code>@UlisesGascon</code></a> in <a href="https://redirect.github.com/expressjs/multer/pull/1468">expressjs/multer#1468</a></li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
