The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

is a conventions and helpers gem for building web pages.
Affected versions of this Gem are vulnerable to Cross-site Scripting (XSS) attacks via unescaped quotes when used as attribute values in tag helpers.
Text declared as "HTML safe" when passed as an attribute value to a tag helper will not have quotes escaped which can lead to a Cross-site Scripting (XSS) attack. Impacted code looks something like this:
content_tag(:div, "hi", title: user_input.html_safe)
Some helpers like the sanitize
helper will automatically mark strings as "HTML safe", so impacted code could also look something like this:
content_tag(:div, "hi", title: sanitize(user_input))
All users running an affected release should either upgrade or use one of the workarounds immediately.
You can work around this issue by either not marking arbitrary user input as safe, or by manually escaping quotes like this:
def escape_quotes(value) value.gsub(/"/, '"'.freeze) end
content_tag(:div, "hi", title: escape_quotes(sanitize(user_input)))
