CVE-2026-49323: 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.
The exploitability of CVE-2026-49323 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-49323 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-49323, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-49323, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
