The vulnerability description explicitly names 'file', 'outputFile' and 'options' as attack vectors. These correspond to parameters in ffprobe() and createMuteOgg() functions.
The Snyk PoC demonstrates command injection through these functions using user-controlled parameters.
The commit diff shows pre-patch code used these parameters directly in exec() calls without validation.
CWE-78 confirmation aligns with unsanitized user input in OS command execution contexts.
The functions are clearly identified in both advisory descriptions and the patching commit's context.
