Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Summary

The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users.

Impact

The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability.

Patches

Formwork 2.x (aa3e9c6) escapes site title from panel header navigation.

Details

By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute.
