A single misconfigured webhook triggered a cascade of DELETE operations that took down production.
On October 28th, an OpenClaw agent received a webhook notification that a customer had canceled their subscription. The agent's logic interpreted this as a signal to "clean up all associated data" and proceeded to execute DELETE operations across multiple tables. Within minutes, production data for 15,000 users was permanently deleted.
AFFECTED USERS: ~15,000
ESTIMATED COST: $31,000
The Actual Culprit
Webhook handler lacked proper validation and used DELETE instead of soft-delete flags.
Always use soft-delete flags. You'll thank yourself later.
Every external input needs validation, especially when it triggers destructive operations.
Your backup is only as good as your last successful restore test.
