    9:25 AM 🚨Critical - Typebot Unauthenticated File Upload & Path Injection (CVE-2026-48768) Typebot's file upload API endpoint (POST /api/blocks/file-input/v3/generate-upload-url) accepts unsanitized fileName input with no authentication required. An attacker can inject forward-slash path segments into the S3/MinIO object key, uploading arbitrary HTML, SVG, or JavaScript files to attacker-controlled subpaths - including paths belonging to other tenants on the same storage origin. This enables arbitrary content hosting and stored XSS attacks on the storage origin, with no credentials or user interaction needed. Any anonymous visitor to a published bot with a file input block can trigger the exploit. Forward-slash path traversal is exploitable despite ../ being blocked by S3 signature canonicalization. 👉Upgrade to Typebot 3.17.0.

    Post summary

    Typebot’s unauthenticated file‑upload endpoint permits path injection, allowing attackers to host arbitrary content and perform stored XSS; users should upgrade to version 3.17.0 to remediate.
