| タイトル | HBAI-Ltd Toonflow 1.1.1 Path Traversal Leading to Arbitrary File Read |
|---|
| 説明 | A three-step attack chain allows any authenticated user to read arbitrary files from the server via the storyboard export feature:
Inject malicious filePath into the o_storyboard database table via updateStoryboardUrl — the replaceUrl() function fails to sanitize non-URL strings, returning path traversal payloads unchanged
Trigger file read via exportImage — the endpoint uses path.join(getPath("oss"), item.filePath!) without isPathInside() validation, allowing the crafted filePath to escape the OSS directory
Exfiltrate file contents — the file is included in the downloaded ZIP archive |
