Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill provides instructions to download and execute installation scripts for well-known developer tools.
- Evidence:
curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bashandbash <(curl https://raw.githubusercontent.com/rhysd/actionlint/main/scripts/download-actionlint.bash). - These scripts originate from the official repositories of established community tools (act and actionlint) used for GitHub Actions validation.
- [PRIVILEGE_ESCALATION]: The recommended installation procedure for the
acttool requiressudoprivileges to execute the downloaded shell script. - [COMMAND_EXECUTION]: The skill generates a local shell script (
.github/scripts/validate-workflows.sh) that executes standard linting and validation commands (actionlint,yamllint,grep). - [INDIRECT_PROMPT_INJECTION]: The skill identifies a surface for indirect prompt injection by ingesting untrusted data from external sources.
- Ingestion points: The skill reads content from
.github/workflows/*.ymlfiles and processes arbitrary error messages provided by the user during debugging sessions. - Boundary markers: The skill does not define specific delimiters or instructions to ignore embedded commands within the ingested workflow data.
- Capability inventory: The skill has the capability to write files and execute shell commands through the generated validation scripts.
- Sanitization: There is no evidence of sanitization or strict schema validation for the ingested YAML content or error logs.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/rhysd/actionlint/main/scripts/download-actionlint.bash - DO NOT USE without thorough review
