Real-World Exposure

1 pkg affected

🐘ezsystems/ezplatform-richtext

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

The rich text editor does not escape attribute data when previewing custom tags. This means XSS is possible if custom tags are used, for users who have access to editing rich text content.
