Vulnerability details

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.

Why these techniques?

Argument injection into ExifTool via Node.js library enables attacker-controlled file reads/writes from the process context (T1005) when untrusted strings reach the affected APIs (T1059.007).
