CVE ID :CVE-2026-44563 Published : May 15, 2026, 8:16 p.m. | 1 hour, 8 minutes ago Description :Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the /api/generate, /api/embed, /api/embeddings, and /api/show endpoints accept any model name from the user and forward the request to the Ollama backend without checking whether the user is authorized to access that model. These endpoints only require get_verified_user (any authenticated non-pending user) and validate that the model exists in the full unfiltered model list, but never check AccessGrants.has_access(). This vulnerability is fixed in 0.9.0. Severity: 5.4 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
