A new study reveals that many software vulnerabilities in modern vehicles stem from external open-source libraries used during development. Researchers identified 827 vulnerable libraries across 20 projects, underscoring potential digital risks for connected car owners.
Why it matters
As modern vehicles rely increasingly on complex software for critical functions, reliance on external code introduces security gaps that can be exploited by bad actors. Understanding these risks helps owners identify why software updates are essential for long-term vehicle safety and digital security.
Researchers identified 827 vulnerable libraries across 20 open-source projects used in automotive software, with 17 of these flaws appearing in the US cybersecurity agency catalog of known exploited vulnerabilities.
The players
University of Gothenburg
A Swedish research institution that investigates software engineering and cybersecurity trends.
Chalmers University of Technology
A research university in Sweden focused on technical innovation and software security protocols.
The details
Security researchers analyzed automotive software development data to find that the majority of security flaws originate during the initial code-writing phase. By scanning open-source projects, the team found that many vulnerabilities are imported through third-party libraries rather than being built into the proprietary systems of the car manufacturer. This means that software security depends not just on the automaker, but on the integrity of the broader software ecosystem used to build vehicle systems.

The Home Front
This research follows a decade of industry concern regarding connected vehicle security, building upon the precedent set by the 2015 Jeep Cherokee remote access demonstration. It highlights a shift in risk management where software supply chain integrity is now as critical as physical automotive engineering.
Vehicle owners should prioritize installing manufacturer-issued software updates promptly, as these often patch discovered security flaws. Check your vehicle's infotainment settings or the manufacturer’s app to ensure your car is configured to receive the latest security patches over-the-air.
The takeaway
The security of your vehicle is increasingly linked to the vast network of external code used during its development. Ensure you remain registered with your automaker so you receive timely notifications regarding software updates that address critical security flaws.
