How Agentic Vector Databases Leak API Keys via Error Logs
A developer warns that AI agents storing error messages in vector databases can inadvertently expose API keys. A failed API call with a verbose error containing a key gets saved to memory, then retrieved weeks later by a prompt injection. The proposed fix is active transport-layer redaction before the key enters the agent's context.
