Description
Lotus through 0.10.2 contains an improper authentication vulnerability in the Go event ingestion middleware that validates API keys by prefix only, without checking the secret against the stored hashed_key. Attackers who know or obtain an API key prefix can submit usage events to POST /api/track/ as that organization, altering its metered usage and billing.
