CVE-2025-31114Network attack vector

Remote code execution via metadata eval injection

Published Aug 11, 2026 · Updated Aug 11, 2026

Eval injection in lllyasviel Fooocus 2.5.5 and earlier allows remote attackers with web UI access to execute code through image metadata. The load_parameter_button_click path passes attacker-controlled styles, resolution, adm_guidance, and freeu values from uploaded-image metadata to Python eval. The web UI listens on localhost by default, but --listen and --share exposures are unauthenticated unless basic authentication is configured, and successful exploitation runs code in the Fooocus process context.
