CVE-2026-3828Network attack vector

Authenticated command execution via malicious packet data

Published May 9, 2026 · Updated May 9, 2026

OS command injection in Hikvision DS-3E1310P-SI, DS-3E1318P-SI, and DS-3E1326P-SI allows remote authenticated users to run arbitrary commands. The packet-processing code insufficiently validates command-bearing data before operating-system execution; Hikvision has not named the handler or parameter. Network access and valid device credentials are required; affected firmware is 1.2.4_210623 and earlier for DS-3E1310P-SI and 1.2.0_210823 and earlier for the other models.
