LOW 3.5

Gitea Jupyter notebook UI redress through CSS class injection

CVSS Score

3.5

EPSS Score

0.0%

EPSS Percentile

0th

Gitea's Jupyter notebook renderer inserts the notebook's language_info.name metadata into a CSS class attribute while disabling sanitization and rendering directly in the main document without an iframe sandbox. A malicious repository notebook can supply multiple CSS classes that create a viewport-covering overlay and intercept clicks when another user views it. The reported impact is UI redress; script execution was not demonstrated.
