Developer Action Items
- ☐ Inventory whether Google runs in prod, CI, staging, or on laptops before you debate severity.
- ☐ Confirm the vendor's fixed build for Google from TechCrunch, then schedule the patch window.
- ☐ If you cannot patch today, isolate the service, rotate tokens that sat on the affected surface, and raise the logging floor.
- ☐ Record the decision and residual risk so the next on-call does not re-litigate whether you are exposed.
