Bug: Command injection vulnerability in package name
The package name field contains shell command syntax including a semicolon, echo command, and comment character. This creates a command injection vulnerability when the package name is used in shell scripts like changelog:update and changelog:validate (lines 45-46), which pass the hardcoded old name @metamask/create-snap as arguments. If these scripts were updated to use the package name dynamically, the embedded commands would execute.

Bug: Package name contains shell injection characters
The package name h1-poc; echo '--- H1-VERIFICATION-LOG-BY-ANOMALY-ZERO ---'; # contains shell metacharacters (semicolon, hash) that could be interpreted as command separators by shell scripts or package managers. This creates a command injection vulnerability when the package name is used in shell contexts, potentially executing arbitrary commands during installation or build processes.

Bug: Command injection payload in package name
The package name contains shell command injection syntax with a semicolon, echo command, and comment character. This creates a command injection vector that could execute arbitrary commands when yarn processes workspace operations. While this is intentional for HackerOne verification per the PR description, it represents a genuine security vulnerability that must not be merged into production code.
