CVE-2026-49316 · Severity: medium · CVSS 4.6 · Published 2026-05-29

A security flaw in the 2025 Indian Motorcycle Scout Bobber + Tech model allows an attacker with physical or local network access to bypass the vehicle's anti-theft system. By disrupting the motorcycle's internal communication network, an attacker can prevent the security module from sending a shutdown command, allowing the bike to be started and ridden without a valid key. This poses a significant risk of vehicle theft and unauthorized operation.

## Technical details

The vulnerability stems from an expected behavior violation in the CAN bus implementation of the Wireless Control Module (WCM). An attacker can use a CAN error-frame injection technique to target periodic WCM transmissions, driving the transmit error counter (TEC) past the bus-off threshold (255). Once in the 'bus-off' state, the WCM ceases all transmissions, including the immobilizer's shutdown command. Because peer Electronic Control Units (ECUs) do not treat the absence of WCM messages as a security exception, they continue normal operation, effectively bypassing the anti-theft mechanism. This requires adjacent network access to the vehicle's CAN bus.
