Description

@runnerty/executor-decompress through 3.1.1 contains an OS command injection vulnerability that allows attackers to execute commands by supplying crafted archive file names to compress_file. Attackers who can name a file dropped into a watched directory can inject $() substitutions or unquoted shell metacharacters into shelljs exec() calls, running commands with Runnerty process privileges.
