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). Any authenticated user can invoke getSetupData with an arbitrary userId to read that user's live TOTP secret, or disable2FA to strip another account's two-factor authentication entirely, fully defeating account-level 2FA protection. This is related to CVE-2026-15509, which covers a similar missing-authorization pattern in the JSON-RPC editUser/addUser role-assignment path in the same application; the TwoFA service methods addressed here are a distinct, independently fixable set of RPC endpoints.
