Report: CVE-2026-5026 - Langflow - Stored XSS via Malicious SVG Upload
CVE ID :CVE-2026-5026 Published : March 27, 2026, 3:17 p.m. | 29 minutes ago Description :The '/api/v1/files/images/{flow_id}/{file_name}' endpoint serves SVG files with the 'image/svg+xml' content type without sanitizing their content. Since SVG files can contain embedded JavaScript, an attacker can upload a malicious SVG that executes arbitrary JavaScript when viewed by other users, leading to stored cross-site scripting (XSS). This allows stealing authentication tokens stored in cookies, including JWT access and refresh tokens.
