■ AI-SUMMARIZED FROM 3 SOURCES ▸ TIMELINE

Security researchers have discovered a bootloader vulnerability in Tesla Wall Connectors that allows attackers to bypass firmware downgrade protections. The flaw, detailed in a technical report from Synacktiv, could enable unauthorized modifications to the charging hardware.

The vulnerability exists in the bootloader of Tesla's Wall Connector, the home charging station sold with Tesla vehicles. Researchers found that the firmware downgrade ratchet—a security mechanism designed to prevent installation of older, potentially vulnerable firmware versions—can be circumvented through bootloader-level exploitation. According to the published technical analysis, an attacker with physical access to the Wall Connector's charge port connector could potentially manipulate the device's firmware. This could theoretically allow installation of compromised software or extraction of sensitive data. The discovery was disclosed through responsible disclosure practices. Tesla has not yet issued a public statement regarding the vulnerability or availability of patches. Wall Connector owners are currently advised to monitor Tesla's security updates. The finding adds to recent security disclosures affecting Tesla infrastructure, highlighting potential gaps in hardware security practices across the company's product line.
