Kia’s Web Portal: Register Any Car’s Account, Control It From Your Phone
On September 25, 2024, researchers Karan Saini and Sam Curry published an access-control flaw in Kia's dealer and consumer web infrastructure: given only a license plate, an attacker could register an account with remote lock, unlock, start, stop, locate and horn control over 2014-2025 connected vehicles they did not own. Kia patched in August before disclosure. This account walks the plate-to-command chain, the ownership-verification gap, the threat model for tracking and theft, and the automotive-API authorization lesson that outlasts the brand.
