  "details": "Action View is a framework for handling view template lookup and rendering and provides view helpers for building HTML. Prior to 8.1.4.1 and 8.0.5.2, strip_tags in Action View returns its sanitized output marked html_safe, but the underlying sanitizer encodes only \u0026, \u003c and \u003e, leaving \" and ' unencoded. Because ERB does not escape a string marked html_safe, untrusted input passed through strip_tags and rendered inside a quoted HTML attribute value could close the attribute and add new attributes, possibly leading to XSS. Applications that render strip_tags output from untrusted input inside an HTML attribute, for example in a title attribute or a \u003cmeta content\u003e tag, are affected. Output rendered as element content is not affected. This issue is fixed in versions 8.1.4.1 and 8.0.5.2.",
