提交 #908266: volotat Anagnorisis 0.4.0 Path Traversal

An improper file boundary validation vulnerability exists in volotat Anagnorisis 0.4.0. Multiple Socket.IO handlers accept client-controlled file paths and use them for file reads, writes, moves, metadata sidecar access or video-stream registration without canonicalizing the path and verifying that it remains under the configured media directory.

The affected operations include the text get_file_content and save_file_content events, the image move_files event, the video start_streaming event, shared image/music/video metadata handlers, and optional trash handlers when file deletion is enabled. These locations share the same missing directory-containment security boundary and are reported as one vulnerability.

The issue was reproduced independently of the separate Socket.IO authentication flaw by using a validation harness that rejects unauthenticated clients and accepts only an authorized client. The original text handler overwrote a synthetic module page outside the configured media root. Anagnorisis reads module page.html files and passes their content to render_template_string, so the safe proof of concept wrote only the arithmetic Jinja expression {{ 7 * 7 }} and observed the rendered value 49. Separate source-exact tests confirmed moving a synthetic outside file through the image handler and registering an outside synthetic video path for streaming. No operating-system command execution or real sensitive file access was attempted.
