Real-World Exposure

1 pkg affected

🐘ezsystems/ezplatform-admin-ui

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

It is possible to inject JavaScript XSS in the content type entries "name" and "short name". To exploit this, one must already have permission to edit content types, which limits it in many cases to people who are already administrators. However, please verify which users have this permission. The fix ensures any injections are escaped.
