CVE-2026-64677
Anki's local HTTP server is vulnerable to directory traversal attacks
Description
Anki is a program for creating and reviewing flashcards. Prior to 25.09.3, endpoints in Anki's local HTTP server do not adequately constrain requested media and built-in data paths, allowing scripts served from shared decks, or malicious websites combined with an origin-check bypass, to read local files through directory traversal. This issue is fixed in version 25.09.3.
