CVE-2026-43893 · exiftool-vendored: Argument injection via newline characters in tag names

This page contains facts from public vulnerability sources. Check the original advisory before updating.

exiftool-vendored provides cross-platform Node.js access to ExifTool. Prior to 35.19.0, exiftool-vendored starts ExifTool in -stay_open True -@ - mode, where arguments are read from stdin one per line. In affected versions, several caller-supplied strings were interpolated into ExifTool arguments without rejecting line delimiters. A newline or carriage return inside one of those strings could split a single intended argument into multiple ExifTool arguments, allowing argument injection. The fix also rejects NUL bytes as unsafe control characters. Applications that pass attacker-controlled strings to affected APIs may allow an attacker to make ExifTool read files accessible to the ExifTool process, or write output to attacker-chosen file system paths accessible to that process. No remote code execution has been demonstrated. This vulnerability is fixed in 35.19.0.
