Security readout for executives and security teams
Plain-English summary
This flaw affects the 2025 Indian Motorcycle Scout Bobber + Tech. Someone physically near the motorcycle with access to observe the in-vehicle network could recover the user unlock PIN from one legitimate authentication exchange. The issue weakens the bike’s primary user-authentication control, but the published CVSS indicates physical proximity and user interaction are required.
Executive priority
Treat as a moderate, physical-proximity risk. It is not a broad remote compromise based on current evidence, but it can defeat a primary authentication control on affected motorcycles. Prioritize vendor confirmation and service updates for owned or fleet vehicles.
Technical view
The WCM uses weak authentication with the Infotainment Digital Round display. The response is computed using a non-cryptographic operation instead of a cryptographic challenge-response, making the PIN mathematically derivable from a single observed exchange. Protocol specifics are withheld pending vendor remediation. CVSS v3.1 is 4.3: AV:P/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N.
Likely exposure
Exposure appears limited to Indian Motorcycle Scout Bobber + Tech model year 2025. The attacker must be adjacent or physically positioned to read the in-vehicle network and observe a PIN authentication exchange.
Exploitation context
The sources do not report active exploitation, and the CVE is not listed as KEV in the provided bundle. Exploitation requires passive observation of a legitimate PIN exchange and access close enough to read vehicle-network traffic.
Researcher notes
The advisory identifies CWE-1390, CWE-294, and CWE-327. Detailed protocol information is intentionally withheld, so independent validation should avoid reconstructing or publishing attack details. Evidence supports confidentiality impact through PIN recovery, with no integrity or availability impact claimed.
Mitigation direction
- Check Indian Motorcycle or Polaris guidance for firmware updates or service actions.
- Ask dealers whether WCM or infotainment software updates address CVE-2026-49322.
- Limit unauthorized physical access to the motorcycle until vendor remediation is confirmed.
- Avoid entering the unlock PIN in untrusted service or public environments when possible.
Validation and detection
- Inventory whether any fleet motorcycles are Scout Bobber + Tech 2025 models.
- Record current WCM and infotainment software versions through approved service channels.
- Confirm with the vendor or dealer whether the installed versions are affected.
- Track CVE-2026-49322 for updated remediation details from the advisory or CVE record.
