What to do

1. Check whether you run it. Look for Vitejs in your asset inventory, including appliances and cloud images. Stack check lists every exploited Vite CVE at once.
2. Apply the fix. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 31 Mar 2025.
4. Get told next time. Email alerts when CISA adds a CVE for Vite.
