CVE-2026-90926Network attack vector

Authenticated code execution via undisclosed injection path

Published Sep 28, 2026 · Updated Sep 28, 2026

Code injection in Logsign SIEM 6.4.101 through 6.4.116 allows remote authenticated users to execute injected code via a network interface. The CNA does not identify the component, request field, or code-generation operation that mishandles attacker-controlled input. Low-privilege access is required; the precise execution context and reachable feature remain undisclosed.
