Report: Breaking: CVE-2026-45314 - Open WebUI: XSS via SVG in /api/v1/channels/webhooks/{webhook_id}/profile/image

CVE ID :CVE-2026-45314 Published : May 15, 2026, 10:16 p.m. | 1 hour, 9 minutes ago Description :Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, the channel webhook create/update flow accepts arbitrary profile_image_url values, including data:image/svg+xml;base64,... payloads. The profile image endpoint then decodes and serves this SVG as image/svg+xml without sanitization, allowing attacker-controlled script handlers (for example onload) to execute when the profile-image URL is opened in the browser. This vulnerability is fixed in 0.9.3. Severity: 7.4 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...
