Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary commands and cause a denial of service.
The vulnerability exists due to improper neutralization of special elements in ExifTool argument handling in gotenberg when processing metadata values containing newline characters from user-supplied input. A remote attacker can supply a specially crafted metadata value to execute arbitrary commands and cause a denial of service.
The issue is a bypass of the key sanitization logic for stdin arguments via metadata value newlines.
