Summary

CVE-2026-7694 is a medium-severity Injection (CWE-74) vulnerability in Feishu (inferred from references). Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 2.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-7694 is a SQL injection vulnerability (CWE-74, CWE-89) in Acrel Electrical ECEMS Enterprise Microgrid Energy Efficiency Management System version 1.3.0. The issue resides in an unknown function of the file /SubstationWEBV2/main/elecMaxMinAvgValue, where manipulation of the fCircuitids argument triggers the injection.

The vulnerability is remotely exploitable by unauthenticated attackers with low attack complexity and no user interaction required, per its CVSS 3.1 score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Exploitation enables limited impacts on confidentiality, integrity, and availability through SQL injection.

Advisories indicate no vendor response despite early contact, with no patches or mitigations detailed. An exploit has been published and may be used, as documented in references including VulDB entries and a Feishu wiki.

Notable context includes the public availability of the exploit, increasing risk for exposed instances of this energy management system.
