Authenticated arbitrary file read via unchecked export path
Published Apr 27, 2026 · Updated Apr 27, 2026
Path traversal in Toonflow 1.1.0 through 1.1.1 allows remote authenticated users to read server files through Storyboard Export. replaceUrl returns a non-URL value unchanged, updateStoryboardUrl stores it as filePath, and exportImage joins that path without enforcing the OSS boundary before adding the resolved file to a ZIP. Successful exploitation requires a valid JWT and a reachable API; the vendor disputes practical exposure because the interface expects local or Docker-configured trusted addresses.
