Summary
Weblate: Stored HTML injection in editor search preview
Details

Impact

Weblate's live search preview renders unit source and context as HTML without escaping. Any contributor whose content reaches those fields stores HTML and CSS that runs inside the authenticated editor of every user who runs a matching search.

Patches

Workarounds

Only the search preview on the selected views is affected.
