coverage is vulnerable to Cross-Site Scripting (XSS)
76
High Risk
This Affects:
coverageTL;DR
When coverage generates an HTML report with show_contexts enabled, it embeds context labels into the report without sufficient HTML escaping. A crafted context label can break out of its enclosing inline element and inject arbitrary markup into the generated report. Any user who opens the HTML report in a browser is exposed to the injected content. The fix fully HTML-escapes context labels before embedding them into the report.

You are affected if you are using a version that falls within the vulnerable range.
