Denial of service in file-type library versions prior to 21.3.1 allows remote attackers to hang Node.js event loops by submitting malformed ASF (WMV/WMA) files that trigger infinite loops during file type detection. Applications using file-type to analyze untrusted input are vulnerable, with a minimal 55-byte payload sufficient to stall processing. No patch is currently available for affected Node.js and File Type products.
A malformed MKV file can trigger an infinite loop in the file-type Node.js package (versions before 16.5.4 and 17.x before 17.1.3), causing application unresponsiveness and enabling denial-of-service attacks. The vulnerability affects the Sindresorhus file-type library, a widely-used dependency for file type detection, and requires only local access and user interaction to trigger (CVSS 5.5). With an EPSS score of 0.17% (38th percentile), actual exploitation probability remains relatively low despite the moderate severity rating.
