Description

Leantime through 3.6.2 exposes the JSON-RPC methods leantime.rpc.TwoFA.TwoFA.getSetupData, saveSecret, verifyAndEnable, and disable2FA, which act on a caller-supplied userId parameter with no ownership check, session pinning, or permission-attribute gate (unlike other RPC-exposed methods in the same dispatcher).
