mediawiki/semantic-media-wiki is vulnerable to Cross-Site Scripting (XSS)
61
Medium Risk
This Affects:
mediawiki/semantic-media-wikiTL;DR
The property value autocomplete copies a suggestion from the API into the dropdown markup without HTML escaping when the query is empty. A stored property value that contains markup is then shown as HTML to the next user who opens the widget, leading to cross-site scripting. The fix escapes suggestion values before inserting them.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and the property value autocomplete widget is enabled.
