Vulnerability from github – Published: 2026-09-14 18:31 – Updated: 2026-09-14 21:31

Details

This vulnerability is due to insufficient validation in the email parsing logic. An attacker could exploit this vulnerability by sending a crafted email message that contains malicious SQL statements through an affected device. A successful exploit could allow the attacker to execute arbitrary SQL statements, leading to command execution with root privileges on the underlying operating system.

Severity

9.8 (Critical)
