Summary
Harden input handling in
cli/action.yml(flagged by semgrep).Vulnerability
yaml.github-actions.security.gha-curl-pipe-shell.gha-curl-pipe-shellcli/action.yml:62Description: A
run:step pipes the output ofcurlorwgetdirectly into a shell interpreter. This is the "curl | bash" install pattern — if the remote server is compromised or the URL is hijacked, an attacker can execute arbitrary code in your CI runner. Consider downloading the file first, verifying its checksum or signature, and then executing it.Threat Model Context
This is a private Node.js application (not published to npm). Vulnerabilities affect this application's own runtime only.
Changes
cli/action.ymlBehavior Preservation
The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.
