GHSA-rqj7-6wrp-6g2g: Open WebUI: POST /api/v1/images/edit bypasses the global image-edit switch and the per-user image-generation permission
Summary
POST /api/v1/images/edit performed no authorization beyond requiring a verified account. Every other image-editing surface in Open WebUI enforces the global image-edit switch and the per-user image-generation permission — the /api/v1/images/generations route, the built-in edit_image tool, and the chat image-edit middleware — but the direct edit route enforced neither. A verified non-admin user could therefore invoke server-side image editing, reaching the configured image-edit provider with the administrator's credentials, even when the administrator had globally disabled image editing (ENABLE_IMAGE_EDIT=False) or denied that user image-generation permission. The image-editing UI is surfaced only to administrators (Playground), so the route additionally exposed an admin-only capability to any verified user.
Impact
An authenticated, non-admin user can:
- bypass the global ENABLE_IMAGE_EDIT=False administrator control;
- bypass a denied per-user/group features.image_generation permission;
- cause the server to send billable image-edit requests to the configured provider (OpenAI-compatible, Gemini, or ComfyUI) using administrator-configured credentials (IMAGES_EDIT_OPENAI_API_KEY for the OpenAI engine).
No cross-user data is exposed and the provider credentials are never returned to the caller; the impact is the control/permission bypass and the associated billable resource consumption.
Affected Versions
= 0.8.11, < 0.10.0 (the /api/v1/images/edit route was introduced in 0.8.11 and was ungated from the outset). Fixed in v0.10.0.
Details
/api/v1/images/generations enforces ENABLE_IMAGE_GENERATION (403 if globally disabled) and features.image_generation (403 for non-admins without the permission). The edit_image built-in tool and the chat image-edit middleware likewise gate on ENABLE_IMAGE_EDIT and features.image_generation. The direct POST /api/v1/images/edit route ran on Depends(get_verified_user) alone and proceeded straight to provider dispatch, appl
