mediawiki/semantic-media-wiki is vulnerable to Cross-Site Scripting (XSS)
61
Medium Risk
This Affects:
mediawiki/semantic-media-wikiTL;DR
JsonResultPrinter returns the default parameter unchanged when a query has no results and the output mode is SMW_OUTPUT_FILE. Special:Ask serves that response without a Content-Type header, so the browser parses it as HTML and runs the reflected markup, leading to cross-site scripting. The fix escapes default before writing the file output.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
