CVE-2025-67862

Administrator Lua execution via restricted CLI escape

Published Jun 9, 2026 · Updated Jun 9, 2026

Unsafe debug access in Fortinet FortiOS and FortiProxy allows authenticated administrators to execute Lua scripts through crafted CLI commands. Fortinet identifies a restricted CLI escape and unsafe debug state but has not disclosed which command handler accepts the crafted input or how Lua is invoked. Reachability requires an authenticated administrator CLI session; successful use escapes the restricted command set and runs attacker-supplied Lua on the appliance.
