Description
ezBookkeeping 1.2.0 before 2.0.1 contains a privilege escalation vulnerability that allows attackers holding an API token to obtain a full session token via /api/v1/tokens/refresh.json. Because TokenRefreshHandler never checks token type, attackers can exchange short-lived or IP-restricted API tokens for 30-day normal session tokens that bypass API token expiry and allowlists.
