Changelog Entry
Description
This PR implements backend-side permission enforcement for three key resource-intensive features: Image Generation, Web Search, and Audio (TTS/STT). Previously, these features relied solely on frontend hiding/disabling. This change ensures that even direct API calls respect the global toggle switches (e.g., ENABLE_IMAGE_GENERATION) and granular user permissions (e.g., features.image_generation).
Added
Added has_permission checks to backend/open_webui/routers/images.py around the generate_images endpoint.
Added has_permission checks to backend/open_webui/routers/retrieval.py around the process_web_search endpoint.
Added has_permission checks to backend/open_webui/routers/audio.py for both speech (TTS) and transcriptions (STT) endpoints.
Changed
Updated generate_images, process_web_search, speech, and transcriptions functions to return 403 Forbidden if the feature is globally disabled or the user lacks the specific permission.
Included an explicit bypass for users with the admin role in granular permission checks, ensuring admins retain access even if granular permissions are unset, matching frontend behavior.
Fixed
Fixed a security gap where disabled features could be accessed via direct API calls.
Security
Enforced robust access control for Image Generation, Web Search, and Audio features at the API level.
Breaking Changes
BREAKING CHANGE: Users or scripts relying on accessing these APIs while the feature is disabled in the Admin UI will now receive a 403 Forbidden error. This is corrected behavior but may break existing workflows that bypassed UI restrictions.
Additional Information
Admin users are exempt from the granular permission checks (e.g., checking features.image_generation), but NOT the global toggle checks (e.g., checking ENABLE_IMAGE_GENERATION). If a feature is globally disabled, even admins cannot use it via the API. This aligns with standard security practices where global switches are absolute.
