Arbitrary file read via invalid-path reflection
Published Jul 22, 2024 · Updated Nov 4, 2025
Reflected XSS in the Flask server in Ankitects Anki 24.04 allows remote attackers to read arbitrary files via a crafted flashcard. The invalid-path handler embeds the requested path directly into an HTML 404 response, letting an iframe run script in an authorized context and invoke the image-occlusion API with an unchecked file path. The user must import and review the shared deck; the script can then copy any file readable by the Anki process into collection media and exfiltrate its contents.
