AI Analysis
Technical Summary
CVE-2026-64677 is a path traversal vulnerability (CWE-22) in ankitects Anki's local HTTP server. Before version 25.09.3, the server endpoints do not properly restrict access to media and built-in data paths, enabling unauthorized reading of local files via directory traversal. Exploitation requires user interaction and an origin-check bypass. The issue is resolved in Anki 25.09.3.
Potential Impact
An attacker can read local files on a user's system by exploiting the path traversal flaw in Anki's local HTTP server. This could lead to exposure of sensitive information stored locally. The vulnerability requires user interaction and an origin-check bypass, limiting its ease of exploitation. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade Anki to version 25.09.3 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor's versioning information.
