CVE-2026-56673

ComfyUI is a modular diffusion model GUI, API, and backend with a graph-and-node interface. Prior to 0.28.0, folderpaths.getannotatedfilepath and existsannotatedfilepath join workflow-controlled annotated filenames to a base directory without a containment check, allowing an unauthenticated craft...

CVE-2026-56672

ComfyUI is a node-based diffusion model GUI, API, and backend. Prior to 0.28.0, GET /userdata/file served user-controlled HTML and SVG files with extension-derived content types, allowing stored cross-site scripting in the ComfyUI origin and access to browser-stored API tokens, settings, workflow...

CVE-2026-56671

ComfyUI is a modular diffusion model GUI, api and backend with a graph/nodes interface. Prior to 0.28.0, getmodelpreview in app/modelmanager.py joins an unrestricted filename route capture to a selected model directory without a containment check, allowing an unauthenticated remote attacker to us...
