Summary

Lotus through 0.10.2 contains an improper authentication flaw in its Go event ingestion middleware, which checks API keys only by prefix and never verifies the secret against the stored hashed key. A remote attacker who knows or obtains an API key prefix can submit usage events to POST /api/track/ as that organization, altering its metered usage and billing.
