Summary
Greenshot is an open source Windows screenshot utility. Versions 1.3.310 and below arvulnerable to OS Command Injection through unsanitized filename processing. The FormatArguments method in ExternalCommandDestination.cs:269 uses string.Format() to insert user-controlled filenames directly into shell commands without sanitization, allowing attackers to execute arbitrary commands by crafting malicious filenames containing shell metacharacters. This issue is fixed in version 1.3.311.
