CVE-2026-59227: Openwebui Open Webui

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.11 before 0.10.0, POST /api/v1/images/edit required only a verified account and did not enforce the global image-edit switch or the per-user image-generation permission, allowing a non-admin user to invoke server-side image editing with administrator-configured provider credentials. This issue is fixed in version 0.10.0.
