| 40 | + This PR adds or modifies `allowed_non_write_users`, which allows users without write access to trigger Claude Code Action workflows. This can introduce security risks. | |
| 41 | + | |
| 42 | + If this is a new flow, please make sure you actually need `allowed_non_write_users`. If you are editing an existing workflow, double check that you are not adding new Claude permissions which might lead to a vulnerability. | |
| 43 | + | |
| 44 | + See existing workflows in this repo for safe usage examples, or contact the AppSec team.' | |
