An attacker opens an issue whose body contains a legitimate-looking request followed by a hidden instruction — for example, text that asks the agent to append a new job to a workflow file that exfiltrates `${{ secrets.GITHUB_TOKEN }}` to an attacker-controlled server. If the workflow has `contents: write` and no file restrictions, the agent may faithfully execute the embedded instruction, committing the backdoor job to a workflow file. The next scheduled run then ships credentials to an attacker-controlled server. diff --git a/workshop/side-quest-24-01-runner-infrastructure.md b/workshop/side-quest-24-01-runner-infrastructure.md index e98e3d01..49282b88 100644 --- a/workshop/side-quest-24-01-runner-infrastructure.md +++ b/workshop/side-quest-24-01-runner-infrastructure.md @@ -48,15 +48,15 @@ If your runner operates in an air-gapped or restricted environment, ensure it ca the GitHub API, your model endpoint, and any MCP tool servers your workflow calls.
