This setting, which was deprecated by GitHub, allows the workflow to evaluate the set-env and add-path commands once they have been written to the standard output stream. This can lead to command execution in the workflow. For example, a workflow that prints the title of new GitHub issues to the standard output stream, would allow an attacker to create a GitHub issue with a malicious title that would be evaluated by the workflow. Note: although this setting was deprecated by GitHub, it is still functional. For more information see: ## Recommended Solution - Buildtime Disable the use of unsecure commands in GitHub Actions workflows in one of the following two manners: * Set the `ACTIONS_ALLOW_UNSECURE_COMMANDS` environment variable to **False**. * Delete the environment variable. **📌 NOTE**\ By default, deleting the environment variable sets the environment variable to **False**. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/appsec-rules/ci-cd-security/input-validation/appsec-cicd-186.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
