Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

CVE-2026-43893

Low
0/10

Summary

`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. This affects versions prior to 35.19.0.

CWE-88 - Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')
