Overview

apm-cli is a MCP configuration tool

Affected versions of this package are vulnerable to Symlink Attack during the integration when symbolic links under certain directories are dereferenced and their target file contents are copied into project deployment directories. An attacker can access sensitive files from the host system by crafting a malicious package that includes symlinks pointing to arbitrary files, which are then read and written into the project during installation.
