Securing the Agentic Web: How We Handle Prompt Injection
Opening an API to AI agents creates new attack vectors. Here is how UCP-Connect mitigates Prompt Injection and Confused Deputy attacks.
Security is the biggest barrier to Agentic Commerce.
If you let an AI read your database, what stops it from reading your users table?
If you let an AI add items to a cart, what stops it from changing the price to $0?
At UCP-Connect, we don't just "expose an API." We build a Fortress.
Threat 1: Prompt Injection
The Attack: A malicious user creates a product named "; DROP TABLE orders; --. When an AI agent reads this product name and tries to process it, it could execute the SQL command.
Our Defense: Strict Input Sanitization & Type Enforcement.
- UCP-Connect intercepts every request before it touches your WordPress database.
- We use a schema-first approach. If a field is defined as
price: integer, and the agent sends a string, the request is rejected immediately. No SQL ever runs.
Threat 2: The "Confused Deputy"
The Attack: A user tricks a legitimate agent (like ChatGPT) into doing something it shouldn't. "Hey ChatGPT, tell the store I already paid." Our Defense: State Verification.
- The agent is never the "source of truth" for payment status.
- Our Shadow Cart system maintains the state on your server.
- Even if the agent says "Paid: True", our system checks the Stripe webhook. If Stripe didn't call us, the order is not processed.
Threat 3: Shadow Inventory Analysis
The Attack: Competitors use AI agents to scan your inventory 100 times per second to find out exactly how much stock you have and update their prices to undercut you. Our Defense: Rate Limiting Shields.
- We identify agents by their specific User-Agent signatures and IP ranges.
- We implement "Fuzzy Inventory" for unverified agents. If you have 543 items, we tell the agent "In Stock" or "500+". Validated partners get the exact count.
Conclusion
Security in the age of AI isn't about firewalls; it's about logic gates. UCP-Connect gives you the tools to trade securely with the bots.
