CVE-2026-32630
5.3 · MEDIUMOverview
CVE-2026-32630 is a medium-severity vulnerability affecting sindresorhus file-type. It was published on March 16, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
file-type detects the file type of a file, stream, or data. From 20.0.0 to 21.3.1, a crafted ZIP file can trigger excessive memory growth during type detection in file-type when using fileTypeFromBuffer(), fileTypeFromBlob(), or fileTypeFromFile(). The ZIP inflate output limit is enforced for stream-based detection, but not for known-size inputs. 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. This vulnerability is fixed in 21.3.2.
Remediation
Check the references section for vendor advisories and patches from sindresorhus. Update file-type to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
