CVE-2026-81743Network attack vectorHinoki check available

Code execution via unrestricted log-file path

Published Aug 27, 2026 · Updated Aug 27, 2026

Path traversal in Flowintel 3.3.0 and earlier allows remote authenticated users to execute code through a configurable log-file path. The system_settings_save handler accepts LOG_FILE as an unrestricted string, and logging appends attacker-influenced content to that chosen path. Administrator access is required to redirect the log; execution also requires injected template content to be rendered by the application.
