No affected components available
Summary
Base64-backed media inputs could be decoded into Buffers before enforcing decoded-size budgets. An attacker supplying oversized base64 payloads can force large allocations, causing memory pressure and denial of service.
Attack Scenario Notes
- Recommended deployments bind the gateway to loopback by default and require gateway auth for HTTP endpoints. In that configuration, this is best modeled as a local/authorized DoS.
- If an operator exposes the gateway to untrusted networks (or disables/weakens auth and rate limits), treat this as a higher-severity network DoS risk.
