How to Fix CVE-2024-32152

To remediate this vulnerability, upgrade all affected Anki dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

anki fixed: 24.6 
pip install anki>=24.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show anki

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-32152, inspect your installed packages using pip:

pip show anki

Analyze the terminal output to locate any version of Anki in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 24.6), your application is affected.

Note: The pip show anki command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-184: Incomplete List of Disallowed Inputs, where the product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete. In Anki, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A blocklist bypass vulnerability exists in the LaTeX functionality of Ankitects Anki 24.04. A specially crafted malicious flashcard can lead to an arbitrary file creation at a fixed path. An attacker can share a malicious flashcard to trigger this vulnerability.
