Security Findings3

Severity	Finding	Layer	Location
CRITICAL	Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands.	Manifest	skills/linkerd-patterns/SKILL.md:66
CRITICAL	Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter.	Static	skills/linkerd-patterns/SKILL.md:66
HIGH	Unpinned Remote Script Execution via curl \| sh The skill suggests installing the Linkerd CLI by piping the output of a `curl` command directly to `sh`. This practice, `curl ... \| sh`, executes code downloaded from a remote URL without prior inspection or verification (e.g., checksum, specific version pinning). If the remote server (`run.linkerd.io`) were compromised, or if the script content changed unexpectedly, it could lead to arbitrary code execution on the user's system, posing a significant supply chain risk. Avoid piping `curl` output directly to `sh`. Instead, download the script to a temporary file, inspect its contents, and then execute it. Alternatively, use a package manager if available, or verify the script against a known checksum or specific version before execution.	LLM	SKILL.md:79
