Upgrading Notes

Security: Cross-site scripting (XSS) on text transformations in templates

The default casting for Text and Varchar database field classes usually auto-escapes field values when they are inserted into a template. For some text transformations on those fields, this wasn't correctly applied. The following methods are affected:

  • AbsoluteLinks(),
  • BigSummary(),
  • ContextSummary(),
  • EscapeXML(),
  • FirstParagraph(),
  • FirstSentence(),
  • Initial(),
  • LimitCharacters(),
  • LimitSentences(),
  • LimitWordCount(),
  • LimitWordCountXML(),
  • Lower()
  • LowerCase()
  • NoHTML(),
  • Summary(),
  • Upper()
  • UpperCase()
  • URL()

    If you have used any of these transformations with untrusted values (e.g. from a user-submitted form), please consider updating. More info about SilverStripe's casting logic is available in the "security" documentation.

The page title data wasn't escaped correctly in the SilverStripeNavigator as well as the updated page title in the CMS tree after saving.
