CWE-78Published: April 11, 2026· Updated: Apr 13, 2026

7.5

CVSS v3.1

Official Description

ChargePoint Home Flex revssh Service Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the handling of OCPP messages. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26338.

Technical Analysis

CVE-2026-4157 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.5.

A proof-of-concept (PoC) exploit exists for CVE-2026-4157. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
