Overview

CVE-2026-49323 is a medium-severity vulnerability. It was published on May 29, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

Weak authentication between the Wireless Control Module (WCM) and the Engine Control Module (ECM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the per-vehicle ECM immobilizer secret by passively observing a single seed/key exchange. The WCM derives its response using a reversible, non-cryptographic operation rather than a cryptographic challenge-response, so the persistent immobilizer secret can be reconstructed from one captured exchange. With this secret the attacker can authenticate to the ECM independently of the WCM and start the engine, defeating the immobilizer. Specific protocol details have been withheld pending vendor remediation.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
