Background
Aim is an open-source Python package available on PyPI, designed for managing and analyzing data reports. It provides users with tools to create, view, and manipulate reports efficiently. However, the package has a vulnerability that allows for Cross-site Scripting (XSS), which can be exploited by attackers to execute arbitrary JavaScript in users' browsers.
Vulnerability Detail
The vulnerability arises from a lack of sanitization and sandbox restrictions in the Aim package version 3.28.0. Attackers can submit malicious Python code to the /api/reports endpoint, which is then interpreted and executed by Pyodide when the report is viewed. This allows for the execution of arbitrary JavaScript in the victim's browser, potentially leading to data theft, session hijacking, or other malicious activities.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, avoid using the /api/reports endpoint until the package is updated. Additionally, consider implementing input validation and sanitization on the server-side to mitigate the risk of XSS attacks.
Conclusion
The Aim package is vulnerable to Cross-site Scripting (XSS), which can be exploited by attackers to execute malicious JavaScript in users' browsers. It is crucial to update to a patched version of the package to mitigate this risk. For immediate checks on your application's vulnerability status, consider using Vulert.
