【中危】Anki: User scripts in iframes have access to the internal Anki API

安全速报 · 严重级:中危 · CVSS:6.5 · GHSA-cw6h-ffmh-x6vh

漏洞概要

Summary

Anki's webview-based pages communicate with the Rust backend using an internal localhost API. Anki implements measures to prevent user scripts run in the reviewer/editor from accessing this API (https://github.com/ankitects/anki/pull/3925) but it inadvertently allows access to scripts included via iframes in the editor. While overall only a limited set of API methods are exposed, some such as getImageForOcclusion can read arbitrary files.

CWE: CWE-22 (Path Traversal)
Reporter: Bankde (Eakasit)

Affected Products

Ecosystem	Package	Affected Versions
PyPI	`aqt`	`<= 25.09.3`

Impact

Any desktop Anki user (Windows, macOS, Linux) who imports an untrusted .apkg and views card with an embedded iframe is vulnerable. No special configuration is required. The attacker can read any file accessible to the Anki process and exfiltrate its contents over the network.

Patches

A patch is available in 25.09.4

Workarounds

Do not import .apkg files from untrusted sources.
Inspect .apkg contents (it's a ZIP) for .html/.svg files with <script> tags before importing.
Block unexpected outbound network requests from the Anki process at the firewall level.
