CVSS 3.1
7.6 highCVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:NCVE-2026-54013
High (7.6) in openwebui open webui. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in open-webui 0.9.6.
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, Open WebUI patched SVG XSS in user profile images and webhook profile images but forgot to apply the same fix to model profile images. The ModelMeta class has no validate_profile_image_url field validator, and the model image serving endpoint has no MIME allowlist or nosniff header. Any authenticated user with workspace.models permission (enabled by default) can store a data:image/svg+xml;base64,... payload in a model's profile image and achieve full account takeover of anyone who navigates to the image URL. This vulnerability is fixed in 0.9.6.
