Nearly 1 in 10 Exposed LiteLLM Gateways Accepted the Example "sk-1234" Admin Key

Nearly 1 in 10 exposed LiteLLM gateways accepted the default 'sk-1234' admin key.

Wiz Research found that nearly 10% of internet-facing LiteLLM servers accepted the default 'sk-1234' admin key, which is documented in the setup guide. This key grants full administrative access, allowing attackers to steal API keys, access cloud IAM credentials, and potentially hijack AI model workloads. LiteLLM's security policy states that such configuration errors are out of scope for vulnerabilities.

The lesson from this incident

Full lesson

Nearly one in ten internet-facing LiteLLM deployments accepted the example admin key 'sk-1234' straight from the documentation, granting attackers full administrative access without any exploitation of a software vulnerability. This represents a fundamental configuration management failure: organizations deployed production AI infrastructure using credentials explicitly marked as examples, not secrets. The consequences are severe — attackers can exfiltrate downstream API keys, harvest cloud IAM credentials, and hijack AI model workloads entirely. This incident highlights that as AI tooling proliferates rapidly, security hygiene fundamentals are being overlooked, and vendors disclaiming responsibility for default-credential misuse does not reduce real-world risk.
