Summary
Material for MkDocs: DOM XSS in search suggestions via query parameter
Details

Impact

Material for MkDocs 7.2.0 through 9.7.6 contains a DOM-based cross-site scripting vulnerability in the optional search.suggest feature. A crafted q URL parameter could execute JavaScript in the documentation site's origin after user interaction.

Patches

The issue is fixed in Material for MkDocs 9.7.7. Users should upgrade to 9.7.7 or later.

Workarounds

Sites unable to upgrade should disable the search.suggest feature.
