CVE-2026-8982: Autel Maxicharger Single Charger Firmware: Use of Hard-coded Credentials

CVE-2026-8982 is rated critical with a CVSS v4.0 base score of 10.0 and NVD lists Autel Maxicharger Single Charger Firmware as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

Two undocumented privileged accounts exist in Autel Maxi Charger Single firmware through V1.03.51. The accounts use vendor-defined password derivation mechanisms based on device-specific values, allowing an attacker with knowledge of the algorithm and required inputs to authenticate to the web management interface with administrative privileges.
