Official description

Lotus through 0.10.2 contains an sql injection vulnerability that allows authenticated organization users to inject SQL by registering crafted subscription_filter_keys that bypass keyword-only validation. Attackers can create subscriptions using the malicious key, which is rendered as an unquoted group-by identifier, to inject SQL into usage aggregation queries against the shared multi-tenant database.
