Preventing Privilege Escalation in Autonomous Agent Databases

Attackers can use indirect injection to upgrade an agent's permissions. Learn how ATL-Trust locks database boundaries.

Defending Against Permission Upgrade Injections

If an agent has write access to system configurations, a compromised prompt can direct it to grant administrative privileges to new accounts. ATL-Trust prevents this by enforcing strict, non-upgradeable identity bounds outside the model.

We structure permission controls as immutable rules in the validator manifest. Regardless of what the model generates, the validation node limits the transaction type, blocking administrative changes.

// Identity validation check in logic.rs
if !manifest.allowed_assets.contains(&intent.asset) {
    return Err(ComplianceError::UnauthorizedAssetClass);
}

Enforcing Immutable Identity Manifests

Regardless of instructions within prompt text, the validation node restricts the agent's action classes. Permissions are static, blocking any attempt to write configuration updates, containing the agent's blast radius.

This separation of roles ensures that even if an attacker completely compromises the LLM reasoning core, they cannot escalate privileges to gain full system access.

• Prevents agents from executing administrative functions.
• Maintains zero-trust limits regardless of LLM reasoning shifts.
• Enforces separation of duties at the physical execution boundary.
